Invisible but the mouth

Hi, so I changed outfits and it went back to normal, however, several outfits just show the sim invisible apart from the mouth, so I went into CAS and the invisible outfits weren't there, only there when clicking the sim to choose outfits. 

I never had mods on this save. 

I think it only happens when the sim chooses the invisible "outfit" instead of the other normal ones. 

And its only that one sim.

Thank you.
