Since I started that thread about the zombie eye shadow, I've had it happen a few more times. It seems to be random on the female Sims of the household. Sometimes it happens, sometimes it doesn't. When it does, I usually have to manually put her in each of her outfits, then go to the mirror to unlock the makeup and put the eye shadow back to what I want. It's a tedious process, but once I get each outfit done, they stay in place. The strangest part is that I unlock the pad lock each time, but when I go to the next one, it's locked again.
