After 10 hours of working on the cause of the crash and fixing it, we’re back (total downtime was the better part of a day, sorry). Please please please please please be cautious when building out AE2 systems. Fixing crashes caused by AE2 is the equivalent of brain surgery with a steak knife. Yes, I can remove the tumor but that pesky pink squishy stuff is coming out too… and now you can only smell purple.
While I was working, we updated to 1.4.1 (beta). So there’s that.
