Broken/Updated Mods & CC: Skin Tones, Dec. 2020

@luthienrising I'm trying to figure out which mods are causing Sims Profiles not to show up, and I'm testing my mods right now. It's rather tedious. I know it has to do with custom traits. Have you heard anything about specific mods causing this?
I've tested and ruled out Basemental mods, Wonderful Whims, Meaningful Stories and Mc Command Center. The last two are Sacrificial mods that I'll be testing now, even though their Discord claims they've received no complaints supposedly.
