Thanks for the replies
It really is a huge headache to try to track down, mainly because the crashes were extremely rare to begin with, and with no idea of what section of my mod was causing it there was no way to force the issue to occur in-game to see if any fixes work.
Im actually pretty certain that its not in the DPS system, i added those TargetDPSConfig and PlayerDPSConfig for the sole reason of turning the DPS on and off to see if the crashes occured with DPS off (and they do
)
Oh well, ill find it somehow
