mc1.21.4-2.0.1

Worldthreader 2.0.1 for Minecraft 1.21.4 fixes a few thread-safety issues and adds a new Debug gamerule.
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.

Additions:

• Thread safety for commands related to scheduled events, whitelist, bans etc.
• Debug gamerule to detect both performance and correctness issues. However, there is no guarantee that all issues are
  found.

Fixes:

• Fix ticking time, weather and sleeping players order by updating them in the overworld before updating them in the
  other dimension
• Fix non-world threads being able to request exclusive world access during world tick incorrectly
• Fix F3 debug screen unsafely accessing the server world in singleplayer by not showing that information
• Fix Server console unsafely accessing the overworld to get the spawn position by delaying the access

Known issues:

• Leashed entities going through a portal with the player behaves different from vanilla. When the player goes through
  the portal first, it fails to leash the mobs following the player.
  • Workaround: Let the leashed entities go through the portal first and go through the portal within 5 seconds.
• Ender pearls in dimensions different from the player slow down the game by waiting for exclusive world access to check
  if they should despawn
  • Workaround: /gamerule enderPearlsVanishOnDeath false
