Using one of your builds from actions, I ran into this. It seems to be related to structure gen. The issue is also blaming Snowy Spirit.

I think this can count as solved.

God damnit

This time, it is Biome Makeover.

This is pretty much the same issue as #172, which needs to be fixed in snowy-spirit

So I could fix it easily however I was wondering why that happens in the first place. Is the level RandomSource not safe to call during worldgen or is it not thread safe at all with this. mod?

It is the level RandomSource not safe to call during worldgen.

Ok I see. Must have not been a problem with the old java Random

Looks like the fix is already made (MehVahdJukaar/SnowySpirit@f02e14a). Try reproduce again with that version.

I will get back with you when a crash with another, unrelated mod gets fixed.

The biome makeover bug should be fixed: Lemonszz/Biome-Makeover#179

Closing as fixed

Are you willing to backport fixes to 1.19.2? Namely asking due to the decisions of some mod authors, rendering me stuck and unable to use your stuff.

I don't think Biome Makeover have 1.19.2? What's the "fixes" you are referring to.

Biome makeover does have builds on 1.19.2, and that is what this issue was reported on. In this case, the structure gen crashes.

Here is an updated build of Biome Makeover:
