Skin Tone Glitch

My sims are turning black, it seems to be affecting skin tone. I believe it has to do with the body gloss. However, some of my sims created before the update have also turned black without using the body gloss. It seems to be affecting very fair skin tones. The sims will be fine in CAS, I’ll save just fine, but if I come back to the game the sims are black both in CAS and during play. Skin tone cannot be changed even in full edit CAS mode.
