Underground conversion
I believe the issue here may just be a simple matter of semantics. Even though the biomes are titled "Underground Corruption/Crimson/Hallow", they technically don't start until the layer after the normal underground layer begins- the Cavern. While the materials in the Underground layer are corruptible, they won't be recognized by the game as one of the three special "underground biome" variants. This is why crystal shards stop growing and souls stop dropping above a certain depth. It's just a confusing choice of wording on behalf of the developer that makes the Underground only a relatively small portion of the area below the surface.

 * If you're using the depth meter (and feet), then your stated range of 240 to 840 feet is well within the starting range of the Cavern depth at any world size, except in pretty extreme circumstances. If nothing else, it may be deep enough for actual Underground Corruption/Crimson enemies to spawn nearby and make their way to you. It's most likely just a misunderstanding; the depth required for these biomes is sufficiently deep that many naturally-generated Chasms aren't counted as special underground biomes. You could try checking if the ones that came with your world have the same spawning properties, or if there are any non-corrupted areas at similar depth, check the background to be sure it's not below the transition point between the two depth levels.

 * Right. I think the changes are fine, and the fact that they're a little misleadingly named should probably be indicated in some way. Glad I could help. Gearzein (talk) 04:27, 1 March 2015 (UTC)
