​
Save Compatibility

fCavEX uses custom save formats for some features:
Chest contents and sign text use incompatible binary formats (chests.dat, signs.dat). Already placed chests and signs from vanilla saves need to be broken and replaced.
World generation is not yet implemented. Use freshly created Beta 1.7.3 worlds for best compatibility.

​
Limitations

  • No block update logic (planned)
  • No 2D mobs or combat (planned)
  • Maximum 256 chests/iron chests per world
  • Maximum 256 signs per world
  • Tools are unbreakable (durability system simplified)
  • Double chests not supported
  • Iron doors must be opened manually (no redstone)
