Sim vanished, mouth remaind, then restted to base game

@crinrict 

I played my the save before this bug occurred (this one as well had the two mods I mentioned, MCCC and cake mod) and I noticed two of her everyday clothes were completely randomized. I mean like a normal townie. But I did play a few hours without experiencing the vanishing bug at all. I'll let you know if it happens again. I'll try to do some test runs without the mods too and see if I can pinpoint when and how this happens... if it happens again at all.
