Not sure how this happened, but Cass is stuck with 0/0 health. One hit from anything kills her, and I even attempted Boxing Tape to just knock her out and see what happens. She died.

I've tried everything I can think of to fix this, so I put this to you guys: You know of any way to fix this?

get a better follower.

Cass is like Bender (Futurama) she needs liquor to function keeping her away to long, i.e quitting cold turkey could have horrible side effects
