Patches the materials used by biomes to generate main and sub blocks now cascade and fall the same way slush and rubble does. I would like to know what materials should be affected by this mod, Originally intended to make smoothing the surface for escorting NPCs easier, but there was an accident involving an unexpectedly very deep surface-to-core cave system, an innocent village, and a sinkhole that spread across the entire world. --The copy almost writes itself. (falling blocks spread ores too thin for mining.) Technical details. edit: deleted tag, it was meant for the other mod.
