The only way for me to fix it was to remove all tattoos. First I tried to remove the tattoos one by one and after that in different combos to figure out if one of my cc tattoos was broken but the weird part was that’s the sims didn’t even have any cc tattoos on them. however, they do have custom tattoos made by me and some that I downloaded on the gallery. Other households with Sims with custom tattoos from the gallery have the same problem.
I have the same same problem with pets. I have two cats in one household one of them turned entirely black and I don’t know why because I don’t have any cc for pets. The other cat is fine which is the weird part.
