Hey McJty!

I've had this crash a couple times now. It doesn't seem to be easily replicated and does not happen every single load. But, I still wanted to share it with you just incase you were able to find the crash.

Hmm weird... That shouldn't be possible. I'll check it out

Not sure why it happens but in the next version I have addes some protection against this crash. Not sure when I'll release though as I'm in the middle of huge changes that affect all my mods and so I have to release all my mods at once
