Despawning
Drops on the ground (i.e. not in an Inventory or a storage unit) upon exiting of the world will despawn (disappear). At that point, it is impossible to reacquire them. If there are more than 400 "loose" items on the world, items will also start despawning. In this instance, the items that have remained on the ground for the longest amount of time may vanish as new items are added to the screen.
