Hi, lurker here.
Whenever I load a household from my library into a world, their physical build and faces are changed. Their muscle definition and weight stay the same, however.
I read about bug similar to this on the EA forums, but none of the suggested methods (aside from editing them with the cas.fulleditmode cheat) have worked so far.
I tested it without mods and the results are the same. What's weird is it only seems to reset 3 specific sims, who happen to share a household. I even loaded another household that had one of the sims in it with a few others and the reset only happened to her.
I'm stumped, you guys.
