Crash after enabling gamerule

[skerit]

I got this crash in 1.19 immediately after enabling the gamerule:
This happened after starting the server with DimensionalThreading disabled, and enabling it manually after it has started.

I believe this might be a compatibility issue with ServerCore.
It's caching some values that will get changed by different threads at the same time. Shouldn't be too hard to fix over there.

Issue has been fixed in ServerCore, been using both for a few days now without problems.
