Description
What does this mod do?
This mod adds one mixin that bypasses a certain chunk in serene seasons code that uses a known problematic method, thus preventing server crashes.
Usually the error in server log will look something like this:
[Server thread/ERROR] [net.minecraft.util.thread.BlockableEventLoop/FATAL]: Error executing task on Chunk source main thread executor for minecraft:overworld
net.minecraft.ReportedException: Exception generating new chunk

...at java.base/java.lang.Thread.run(Thread.java:1474) [?:?]

After which the server crashes.

Disclaimer
The mod is very barebones and I do not guarantee that it will fix the issue. From my testing I was able to generate over 200 000 chunks without any problems/crashes (before I made this mod the server crashed after just about 50 chunks were generated), but that does not mean it will fix the issue in your specific case.
Tip:
I reccomend using this alongside WorldGenFeatureFix (not sponsored or anything)
