I guess I don't really know what to call this but I've been coming across massive patches of stone beach biomes all around my world. This is a world generation bug so I don't think it has to do with my system. The issue is very likely related to the fact that stone beaches as a biome have not been removed, and because of the new terrain generation, this has resulted in large patches of stone beaches appearing all around Minecraft worlds. If it continues to exist in future snapshots, let me know. If this is intentional then that's fine but finding that out will confuse me greatly.
