Auto-featured
Download Report

Changelog

Worldthreader 2.4.2 for Minecraft 1.21.8 fixes two threading and compatibility issues. 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

  • Chunk loading deadlock with certain scheduled functions / datapacks
  • Too late world / chunk manager ownership return leading to C2ME and VMP compatibility issues
