Describe the bug
Crash mid-game.

Platform(please complete the following information):

• Minecraft Verison 1.20.1
• Platform Verison 47.4.0
• Mod Version pre14-0-1

Crash report:

crash-2025-09-10_15.14.48-client.txt

Fixed in pre14-0-4

I looked into it carefully, and it’s indeed a bug.
It originates from me passing an incorrect region query object, which is not thread-safe. This can randomly cause crashes if you have Snowy Edge enabled. (Since it’s a rare case, it mainly occurs on your side during block updates. From my experience, the probability is only a few in several thousand — I personally have never encountered it.)

should be fixed in next version

The reason you didn’t encounter issues after updating the mod is that this was already a rare problem to begin with.

fix in pre14-1
