@crinrictI uploaded the sim I started with to my gallery, the household name is Greetings Mort. She is modded because she has a trait from Nisa's mod, which I later removed. (She was able to access the cross stitch box with this trait when I loaded her into the same game/household as the broken sim. I later replaced that trait.
The other cheats I used were to max out the Character Values. The original came with some skills maxed. It's possible I started going through and removing them but gave up.
EDIT: I think your edit and this post might have answered things.
@crinrict I changed her cross stitch skill to 1 and it fixed it. I've never really messed around with skill cheats before so had no idea it could break things like this.
I really appreciate your help!
