The Bug

Sometimes terracotta will generate into caves under the main biome, leaving behind chunks of terracotta (sometimes with red sand on top) with large hard blocky edges.

Could be fixed by building the eroded_badlands biome before carving the caves, instead of the other way round.

Steps to Reproduce

• Make a world with seed 418204909054863755.
• Enter the following command and observe terracotta formations.

• /execute in minecraft:overworld run tp @s 2816.95 48.50 -2988.42 -654.18 -2.97
  /execute in minecraft:overworld run tp @s 2744.76 64.24 -3080.29 -765.57 0.25
  //For the second one look around and behind you, there are more disconnected random lumps and pillars

Observed Behavior

There are random formations with large hard blocky edges.

Expected Behavior

These would not exist
