Known Bugs (Mobile)

This is the list of Known Bugs in the latest Mobile Version of Terraria.

General

 * Players cannot open chests with a pickaxe equipped. (Possibly not a bug; Confirmed on Android and iPhone)
 * Sometimes, when moving items from the inventory/character slot to a chest (or vice versa) by dragging and dropping on the icon (not dragging to the icon, letting it switch over, then dropping it in a slot. You need to drop it onto the chest or inventory icon itself), an item that you move will suddenly cease to exist and not be in your chest/inventory at all. (Confirmed on Android)
 * Often, the framerate will drop and the game will be generally stuttery and slow, until it eventually crashes. This is most notable when underground in the Jungle biome. This is possibly due to a memory leak. (Confirmed on Android)
 * Sometimes armor dyed with different colors will flicker. (Confirmed with a blue Crimson Helmet and yellow Crimson Chestplate and yellow Crimson Greaves on Android)
 * Occasionally black bars will appear in the background, usually going away after a few seconds, or until the player moves away from them. (Confirmed on Android and Kindle)
 * Sometimes the controls don't respond like they should. This includes: the movement stick being stuck moving in a certain direction for a few seconds; sometimes not being able to jump to full height; the Flying Carpet sometimes not responding when the movement stick is held up while in the air; etc.
 * There is a lot of flickering with certain items placed in the world, mainly Golden Chests. (Confirmed on Android)
 * You can not craft some items such as minecarts and tall gates, even when you have all the items for it in your inventory and stand right in front of the correct crafting table.
 * Opening two copies of terraria and then joining the same world may duplicate any item placed down by the non-host player. Placing platinum coins after a few minutes may place without taking from your inventory. (Confirmed when host is on iPod and non-host is on iPad)
 * A cloud-saved world or a cloud-saved character can be lost even though the user did not delete it. (Confirmed on Android, iOS, And Kindle Fire; due to Easter Update) A cloud character can also revert to an older save, causing possible duplication of items in a world. (Confirmed on Android)
 * Occasionally in a corrupt world, the cry of a Face Monster can be heard.
 * When putting the Boots of Ostara item on a mannequin, sometimes it turns into Silver Greaves permanently.
 * In the Android and Kindle Fire version, the game crashes constantly. (A two minute autosave feature was added to combat the loss of items and progress)
 * When you have just crafted a gold crown, dragging it up to your equipment icon, if you have a familiar wig on, will result in the gold crown disappearing, and being replaced with another wig.
 * In the Android version, after playing the tutorial, jumping into the lava at the bottom of the world and being killed, loading a world may cause the game to display " couldn't put the fire out " one or more times.
 * If a host kills another player or if that player dies in multiplayer it will say that the host died.
 * Rarely after beating Skeletron Prime, 1-4 of his explosives may get stuck in the air, this can be fixed by leaving the world and then coming back (Confirmed on iOS).
 * A Demon Altar may spawn missing a quarter of its sprite. After hitting it with a hammer, the player will take damage and the demon altar will be destroyed. If you hit it with the Pwnhammer, it will be destroyed without blessing the world with Hardmode ores.
 * When you teleport using the Magic Mirror and then quickly select a stack of items from the hotbar, you will lose one item from the stack.
 * In the map, the dirt layer below the surface layer is invisible and treated as the sky.
 * When looking at your inventory, items will occasionally appear bigger or smaller in their inventory boxes. (Somewhat fixed, items are not as large/small)
 * Killing players with certain items will result in the tombstone saying the player was killed using something that they weren't killed with. (e.g a Legendary Night's Edge will result in it saying Gold Watch)
 * When using a Thrown Flail, if the player holds their finger on the pad to throw the flail, it will stop moving and sit at their feet (until they move, then it will move around). Do this, then while still holding the button, tap any tool in your hotbar. The tool will flail about, following the flail as you move. While this looks ridiculous, it actually is very effective, as you can have a flail and a sword out at the same time. Furthermore, this will completely negate attack speed. As long as the tool is hitting an enemy, it will do rapid damage. The glitch will end upon A.) removing your finger from the screen or B.) getting the flail stuck on a block and moving too far away. (Works on android, don't know for IOS)


 * When running with the Hermes Boots and flying with any type of wings (for example, Angel Wings) flying up to a one-block wide gap will make you go through the space even though the player is 2 blocks wide.
 * Sometimes, in Hardmode worlds, corrupted/hallowed/chlorophyte blocks won't spread.
 * When creating your character, the undershirt color will always match the overshirt color, no matter what you set the undershirt color to. However, once the character has finally been created, the undershirt color will become what the player had originally set it to.
 * Leggings will sometimes not show up on Mannequins. They are treated as if they were there, however, as they are removed from you inventory upon tapping the said Mannequin and when tapping the legs the leggings will come off (tested with Turtle Armor, Dragon Armor and Spooky Armor)
 * When dying from the chaos state debuff, the death message would be "available for crafting.
 * In the Amazon version, if dye is worn on one of the cloud saved characters it might appear in the dye slot of the player in the tutorial.
 * When you try to write on a sign, it doesn't work (Tested on iPad and Kindle Fire HDX)
 * In the iOS version, if you drag inventory/stored items, when you finish the item will stay highlighted even if you select something else. This can lead to all of the inventory being highlighted. If you select the highlighted item and select something else, or drag another item over a highlighted item, the item will not be highlighted. The issue also ceases when the inventory is closed.
 * In the iOS version, when closing the inventory, sometimes only the walls in the world will be visible, as well as NPCs and entities within chests. The issue resolves by itself after a 1-5 second pause.
 * In the Android version, triggering a toggled off Spear Trap causes the spear-heads to launch upward and pass the trap itself when retracting. It is because the spear-heads actually 'despawn' by hitting a solid block, and the toggled-off Spear Trap no longer serve as the solid block in normal circumstances.
 * In the Android version, Music Boxes disappear from player's inventory when logging out of a world, and seem unable to record music.
 * In the Android version, the Leaf Crystal from Chlorophyte Armor may remain after the armor is taken off, and even after logging off.
 * In the Android version, Soul of Night and Soul of Light can drop in above-ground levels.
 * In the Android and iOS version, Actuators without wires connecting them do not show up when a mechanic item is held in hand. (Wrench, Pressure Plates etc.)
 * In the Android version, it is impossible to place blocks around the left/right/bottom border of the world.
 * In the Android version, placing new blocks in spaces previously occupied by inactive blocks will deactivate them as well.
 * In the Android version, the player can place wire by touch-and-drag across the screen without range restrictions as long as the target location is on screen.
 * In the Android and iOS versions, Ghost Wings' thumbnail in the crafting interface does not darken when not available to craft.
 * In the Android and iOS versions, it is possible to drop down in a one block wide gap by running with Hermes Boots or similar accessories and holding down.
 * Cloud walls are not craftable using clouds. (Tested on iPad)
 * Pickaxe axe found in shadow chest (Kindle Fire HD)
 * In the iOS version, when opening a previously made world half the worlds blocks will not spawn (this is including NPCs, chests etc) and the character will fall to the bottom of the underworld, using rocket boots or a double jump ability you can prevent the character from taking fall damage. It may be possible to get back to the surface by travelling left until the bug ends and you reach solid blocks. At this point enemies will start spawning as usual depending on the biome. There is no fix as of the moment (August 2015). The cause of the bug is unknown but may be related to a bug that creates a new character in place of the old one, with old sprite of the old character showing in the second create player slot. (This bug can be fixed by creating a new player then deleting this player.)
 * Sometimes upon opening a container (e.g. chest, safe, piggy bank) the storage slots will appear in a vertical line. (May be patched)
 * (Multiplayer) When anybody except the host uses a door, the door, and the block it's on would be destroyed.
 * Sometimes, when crafting armor, with armor equip, the armor will disappear (tested on iPod 5, with Turtle Shell and Hallowed Armour).

NPCs

 * Sometimes NPCs glitch into walls, and rapidly move back and forth, making it look like they're flickering. Usually the NPC will get himself/herself unstuck, but sometimes the player may need to remove the section of the wall they're glitched into to get them unstuck. (Confirmed on Android)
 * Quotes sometimes get mixed up among NPCs. For instance the Witch Doctor sometimes says "We have to talk. It's... it's about parties", which is a quote that belongs to the Party Girl.
 * The Dryad Sometimes Say This "Everyone in this town feels a bit off. I woke up to the clothier chewing on my foot last night."While The Truffle Says This "I'll give you a discount on your wears if you can convince (name of Truffle) to come over for a...sizing." Of which is a quote that was supposedly ment to be used by the clothier.
 * The Cyborg sometimes says "DIALOGUE[286]". It is assumed that this is supposed to say "And then Unit 492-8 said, 'Who do you think I am, Unit 472-6?' HA. HA. HA.", since the Cyborg never says this but the Pirate says this instead.
 * The Angler NPC may sometimes say "ANGLER (-1)" in multiplayer worlds.
 * The Nurse sometimes says "I feel like (name of Truffle) is a bit misunderstood, he really is a fun guy" Which is a quote that belongs to the Dryad. (Only happens when Dryad is around)
 * Doors that NPCs regularly use may temporarily become invisible, or sometimes be destroyed and dropped as an item. Occasionally the block directly below the door will be destroyed as well.
 * Teleporters may only work one way for players, but NPCs can be teleported both ways normally.
 * Occasionally, when buying a single item from an NPC, if you have enough money to buy a second item, a second item will be purchased without the player purchasing it. The amount of money required to buy the second item will be lost.
 * If your world has crimson instead of corruption, the guide will still speak of the world as if it has corruption, for example he will tell you to smash shadow orbs even though they don't exist in the crimson.
 * Occasionally, the dryad will tell you "(world name) is 0% corrupt. You should try harder." She will say this regardless of whether you actually do have corruption or hallow in your world.
 * Someone made a typo in the code, and in the New Year's quote the guide says #demolitionist# instead of the demolitionist's name.
 * During the holiday event, Santa will not show up, NPCs will not sell their festive items (roman candle, special clothing, etc.) and the only sign of any event is presents dropping.
 * Pre-hardmode enemies will stop spawning except for rare occasions after hardmode begins, making lenses and black lenses from demon eyes almost impossible to get without going to a new world.(Fixed)
 * If you get Santa, killing him crashes the game. Period.
 * Sometimes the steampunker will say" once you enter the hallowed land, you will see a rainbow in the sky. I can help you in painting that." which should be said by the painter.(android)

Monsters/Bosses

 * If one of The Twins go off the screen, the one that went off the screen will disappear, leaving the player with no items in return. Also, it will not count as a defeat for the three mechanical bosses.
 * Skeletron Prime sometimes does not drop items properly.
 * Killing one of Skeletron Prime's hands may result in the whole Skeletron Prime dying and not dropping anything.
 * When defeating the Wall of Flesh, it will occasionally not drop any items but still cause your world to enter Hardmode.
 * Sometimes hard mode mobs will spawn pre-hardmode, (such as Wraiths spawning at night, Toxic Sludges spawning underground, and Wyverns spawning on floating islands. Occurs only when a hardmode character plays a newly created world or an existing one in pre-hardmode.)
 * Sometimes, the Wall of Flesh will spawn facing in the wrong direction.
 * Zombies will sometimes "glide" (or walk un-animated) backwards. This is triggered by jumping over a Zombie as it attacks you.
 * Killing Piranhas may cause extreme lag.
 * In the Android version, Ice Golems drop Frost Armor pieces instead of Frost Core. (Fixed)
 * Pumpkings' head sprite may not load on the top layer but below the body. This is only cosmetic and will not affect Pumpkings' actions.

Boss-summoning items

 * Ocram will sometimes not spawn after using a Suspicious Looking Skull.
 * When the player uses a summoning item and then quickly taps another item, the summoning item will not be consumed and the boss will be summoned. Furthermore, if you place a stack in the slot where the summoning item was originally located, you may lose an item from the stack.
 * The before mentioned bug works with potions and other consumables, but after going to the main menu and coming back on, or pressing the deposit button in a chest it will disappear.
 * Sometimes, you will not be able to craft the Suspicious Looking Skull even if you have all the materials in your inventory, because for some reason the Mechanical Skull isn't recognized to be in your inventory.
 * Sometimes, using boss-summoning items that require the time of day to be night while it is still daytime will cause the summoning item to be consumed without summoning a boss.
 * Somtimes if two mechanical eyes are in the same chest together, one will randomly disappear after a few minutes.

* When using a spear, and then quickly changing to a pickaxe while the spear is still in use, the pickaxe will be swung continously, but the spear will also keep on being used, as well as with every use going about 1.5 blocks further. Floating heart crystals can spawn on world generation.
 * Sometimes, when looking at a selected weapon/tool, the damage will be the incorrect stat, and when you select another without closing the inventory/crafting menu, other weapons will have similarly incorrect data. The damage for all of these will be scaled, however, and the issue may resolve when the inventory is closed. For example, when crafting the Titanium Sword, the damage read "96" instead of "46," and the Titanium Pick read "52" damage. This is not reflected in-game. It is triggered by tapping an accessory that gives a bonus: if Turtle Armor is clicked, it will re-apply the damage increase. Critical Strike Chance can go up past 100%, and a Terra Blade can appear to do over 2000 damage. This happens when you go to the armor menu.
 * In the Android version, the cost of reforging is five times of the items' sell value.
 * In the Android version, prefixes with any negative value are considered undesirable and are in red texts; hence any reduced mana cost attributes are in red texts instead of green.
 * In the Android version, the Chlorophyte Jackhammer does not function if the user does not use the d-pad and starts it at a wall, but works if started at an empty (wall) space.
 * In the Android version, summoning staffs have no damage listed in the item statistics. Namely the Staff of the Frost Hydra, Slime Staff, Pygmy Staff and Raven Staff. (Fixed)
 * In the Android version, summoning staffs may have negative value for critical strike chance.
 * In the Android and iOS versions, using a spear and simultaneously using a Magic Mirror will cause the spear to fly out of the player's hand
 * Opening the world map and sliding swiftly from the left side of the screen to the top of the screen will cause the map to go black.
 * In the Android and iOS version, minions cannot be cancelled without leaving the world or dying.
 * However if multiple types of minions are summoned interchangeably in quick succession, some if not all minions may despawn.
 * In the Android version, minions may not be replaced in correct summon order when summoned again after reaching the max minions quota (except quota of one, which always replace the minion correctly).
 * Hence it may not be possible to replace some minions for other types without leaving the world, dying, or force despawn by taking minion quotas off.
 * In the iOS version, you are not able to fire cannons nor bunny cannons, no matter how hard you try, it will however fire at random activation. (Confirmed)
