Rystic is working on combing through the entire mod front to back to resolve crashes currently. This is taking significantly longer than expected since while we've solved some of the crashes, not all of them have been resolved, and there isn't necessarily a smoking gun.

I'll be doing a release in the next week or two that should solve some bugs in addition to some of the crashes.

It seems like this is a more recent phenomena with the instability, though I've had periodic crashes every once and awhile going back a very long while.
