Re: sims are pitch black, repairing doesn't help
@oompypoo Pitch-black skin is typically caused by custom content, not a mod per se. But even after you've removed the problem cc, you'd still need to assign a new skin to affected sims, which you can do by taking them into CAS. Some mods allow CAS editing; without mods, you can bring up the cheats console (crtl-shift-C) and enter testingcheatsenabled true , then shift-click on a sim and select "Edit in Create a Sim."
Reinstalling the game doesn't change anything and isn't necessary because this issue exists only in the user files, as in, the Sims 3 folder in Documents > Electronic Arts. At most, you'd need to create a clean folder by moving the existing one elsewhere and allowing the game to spawn a fresh copy, but even that may not be necessary in this case.
