Crashes when editing fairy wings

Mine is now crashing every time I exit CAS trying to update a fairy’s wings. 

I have a household in Innisgreen, had a baby, but it was fine while he was still an infant. He’s a toddler now, no issues. It wasn’t until I tried turning one of his parents into a fairy using the other parent’s ability did this issue start. I can’t edit the turned fairy’s wings or anything. Every time I exit CAS now, it crashes. He’s stuck with the default wings. 

This is on Xbox because I’m honestly too afraid to try it on my computer where all my good files are.
