What's new

  • Fixed a threading conflict that could deadlock or crash the server during chunk autosave. Spawn's block variant-assignment code (Moray Crevice, sea life decorations, sea urchins) occasionally performed unsafe world queries.
  • Block variant assignment is now deferred to run on a normal tick instead of during chunk autosave, and its biome lookup no longer forces a chunk load.
