[FIXED] Muscle mass and definition reset when aging up from teen to young adult

Added

It also happens from young adult to adult. Once my Sim traveled to a different lot they gained all their muscle back.

Very odd seeing your sim go from fairly buff to skinny as a twig lol

Thanks

I invited a Sim to move into my household, then the loading screen came up. When I returned to the game, one of the other Sim's in my house that had been quite muscular was now skinny and bony. I attempted to fix it by going into manage worlds, and into my house then editing it in cas using the cheat to allow me to resize the body. His muscle slider was all the way at the bottom. I thought I could just slide it up and he would return to normal, but all of his muscle definition was gone and his shape was different.
