Sorry I posted the wrong log, here's the most recent, and Tconstruct is not installed.
This happened before so this is the second time its happened, so I'll report this to them if Tconstruction is still the issue.

EDIT: Seems the error is "exception in server tick loop," but making the mods create new configs from scratch hasn't fixed it, so I'm back to being confused.
