So I fell asleep with my server open, and when I woke up the server had crashed, said something about it trying to make a backup using some mod I forgot the name of, I didn't think I needed it so I just tried starting the server again, now it crashes every time on startup, can't find the reason myself in the log. The modpack is Cave Industry
Log from crash - https://mclo.gs/YDAscD7
I transferred to world to a solo save and it says
"Errors in currently selected data packs prevented the world from loading. You can either try to load it with only the vanilla data pack )"safe mode"), or go back to the title screen and fix it manually
Would really appreciate if someone could find the cause and a possible prevention. Thank you much.
