Oh, sorry, I forgot to add that I do not have any custom content what so ever, none, nill, zilch. I use the "No Intro" "mod", but I have downloaded the latest version, compatable with my game, which is also updated to the most recent version. I also use the "NRAAS" master controller mod (also the most recent version, compatable, etc.) from time to time, but this happened only after I have moved my household to a new home, that is the only major change that has occured, I have used the same mods before and when adding sims to the household their avatars were fine.
Also editing a bugged sim in CAS and saving them to the bin results in the saved sim having the same glitched image.
P.S.
Some gem and metal icons are also glitched in the same way.
