Concurrent Chunk Management Engine - Forge

C2ME-Forge 0.2.0-forge.5 (Minecraft 1.20.1) - build 2026-08-31

Compatibility
• Fixed a hard crash on world load when OptiFine is installed. Three mixins
  targeted synthetic lambda methods inside ChunkMap. OptiFine rewrites that
  class, which renumbers those lambdas, and a mixin that cannot find its
  target was fatal. They now step aside instead of crashing. This also
  protects against any other coremod that rewrites ChunkMap.
• Distant Horizons now detects C2ME. DH identifies C2ME by the mod id "c2me",
  but this port used "c2meforge", so every DH version silently failed the
  check and read region files itself instead of going through C2ME. The jar
  now also declares the "c2me" id. Verified with DH 3.2.0 on Forge 47.4.10.

Misc
• Added one line to the title screen splash pool.

Drop-in update - recommended for everyone on forge.4, and required if you use
OptiFine or Distant Horizons. No config changes needed.
