I'm not really sure what's going on, I was originally playing version 0.3.22 but I downloaded a new instance of version 0.4.0 and copied my save over to the new instance to play it. It seems to be okay but now when I load a particular area it crashes. I've attempted to just prune those chunks away as well as the region but it seems to crash on generation now I'm not sure what's going on.

Here is the log: https://paste.ee/p/5Gz82

Okay, while it looks like you've disabled quite a few mods, none of them being disabled should cause a biome generation crash, maybe try re-enabling some of the biome ones and seeing what allows you to generate that area, and what doesn't

I re-enabled Oh The Biomes You'll Go as its the only one I know of what I disabled which uses large-scale destructive chunk generation which is why I disabled it in the 0.3.22 version so if I just want to move my save to a different pack I don't have issues with chunk generation which has worked in older packs.

It seems to have fixed the issue with chunk generation but I don't know why as like I mentioned before moving to the 0.4.0 version I never had it enabled to begin with. So would removing all of the regions that have any OTBYG generation fix the issue and let me remove it again? Or am I still going to have chunk generation issues even then because I removed a large amount of regions in attempt to fix the issue already before coming here.
