Sims changing set outfits when not playing with household
I have a save right now where i'm living in the britechester dorms. Of course the roommates randomly generated were ugly so I gave a few of them a makeover. Now one of them refuses to keep the outfits I have planned for her. I set the exact same outfit for all 5 variants in everyday wear but she will randomly change them to the ugliest stuff possible. When I click on her to fix it, it's like one of the assigned outfits was completely edited.
She is in my households but marked as unplayed. I do use CC, and have used some custom makeup, clothing and tattoos on her. I also have MCCC and Better Build Buy as my only mods. (Note: all other roommates I have edited do not change their outfits like this. I don't think I used much CC on them though besides default skins and eyes which applies to all sims.)
