I've started https://www.curseforge.com/minecraft/modpacks/terrafirmacraft-hardrock (+distant horizons) yesterday and it was all fine. Then a BSOD happened and I went to sleep. Today it was discovered that that BSOD corrupted my save, so I loaded it from backup. But now I'm constantly getting these crashes as in the attachments. I have also deleted and reinstalled my instance in case it was corrupted, but this didn't help.

Yes, this looks like your world is corrupted as it is missing chunk data TFC uses during generation.

Would you be so kind as to describe what exactly should I remove from my save to make it workable again? Meanwhile I have loaded all 5 previous backups (made every 30 minutes) and they all crash when I get close to the same vicinity. The exact chunks are not the same.

Ok, so I have deleted all chunks except closest to my base with MCA Selector, and it helped. Meanwhile, I find it very suspicious that I was able to play for so long with corrupted chunkdata, as it wasn't caused by BSOD since backups were made hours before, and I had no idea of this corruption. I did have a couple "normal" MC crashes though. Is there a tool to check TFC chunk integrity?
