Basin Generation Fix Mod restores natural basin terrain features back into world generation. These rare, small surface shapes strip away the top grass and soil layers of a biome to expose a stony ground floor underneath. Because of an older bug, these patches stopped appearing after the 1.18 update. This mod fixes the issue so you can find rocky clearings across your worlds once again.
