Removed tattoos reappear under certain circumstances

I also had this issue after removing my mods and clearing the ole cache to test some other bugs.  It happened with a sim I had made before release to be a tattoo artist. Loaded her up, decided to replace all her tattoos with custom ones, only for them to pop back up when I switched the outfit. Removing all tattoos also worked for me in the end, just slightly annoying to have to do.
