Worldthreader 2.6.1 for Minecraft 1.21.10 backports several fixes and compatibility improvements from 1.21.11 releases. Please report any issues you encounter to the issue tracker of worldthreader. As worldthreader likely comes with massive mod compatibility issues, please do not report crashes and issues to other mods' issue trackers before confirming the issue without worldthreader.

Fixes

  • Fix a barrier synchronization issue that could leave waiting threads parked.
  • Fix fishing rod owner and state being lost during dimension changes.
  • Work around "Player swapping is already happening!" (issue #44).
  • Preserve teleported entity movement relation using PositionMoveRelation in TeleportedEntityInfo.

Changes

  • Improve compatibility with mods that add and remove worlds dynamically (for example mc-worlds).
  • Improve compatibility with alternative DerivedLevelData implementations.
  • Handle cross-world entity references with fewer exclusive access requests.
  • Move post-teleport additional tick handling into a dedicated tick phase.
