World and tick crashes

Couldn't find a biome with an ID — biome IDs clash

What it looks like in the log

couldn't find a biome with an id of
biome id … conflict

How to fix it

  1. Two mods claimed the same biome ID, or a mod that owned one was removed
  2. Open the config of each biome mod and give them ranges that do not overlap
  3. Changing biome IDs on an existing world changes the terrain that is not generated yet
  4. Putting the removed mod back is the only way to load the world unchanged
