I think this might be it

Thanks! Yeah, that's it.
Does this happen often?

This isn't the log file that contains what you're quoting. Can you find the right one?

Yeah it happens every time the server is loaded. I tried downgrading the mod version to one that worked before but that didn't help so idk if its an issue with another mod too

Can you try removing OPAC? I have a feeling it will still crash.
