Re: does anyone know why my sims keep going bald?
@SheriGR That's the same thing. Add-on packs come with hair, clothing. If you disabled the add-on packs, any sims with hair from those packs would become bald/naked once you saved the game without the packs installed.
It's the same problem with the same solution. Either restore from an older save or manually go through, take them all into cas and set them back up.
What I do in that circumstance? I have a separate world called "Unmodded". If I want to build lots/sims with no mods, I load up that world. Doesn't matter if I save it or not, it's basically only a junk world. If I remove all my mods, I just make sure to load up THAT world and not my main playthrough worlds until I put the mods/cc back in.
Do that. Create a new world called "Base Game". If you remove all your add-ons and packs, make sure to ONLY load up THAT world. Do not load up any of your others until you put the packs back in.
