This might be a bug. A player can't transition from Dripstone Caves to Deep Dark — borders depend on which biome is on top. Fix it so biomes can border naturally.

This might be a bug, let me explain why. A player cannot, for example, transition from Dripstone Caves to the Deep Dark. This means the borders depend on which biome is on top. I want this to be fixed so that these biomes can naturally border each other without issues.
