Worldthreader

Worldthreader 2.0.4 for Minecraft 1.21.4 fixes a minor thread safety issue. 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:

• Add thread-safety to iron golem, snow golem, end portal and wither block patterns used in spawning

Known issues

• When worldthreader is disabled, a player holding a leash going through a portal before the leashed entity causes the leash to break.
