For some reason, any time I go into a new chunk my game crashes. I was originally thinking it was Biomes O Plenty at fault as I had just updated it, but disabling Chisel makes the error non reproducible and I can then enter new chunks without crashing. It may be a Biomes O Plenty issue as well, if it is please let me know and I can post on their GitHub as well. :)

I might know what causes this. Will make the change, and let it get tested

Wait. This report is strange. Did you disable the basalt feature?
