I was playing Pleasantview today and I noticed that at least two male townies with blonde hair (Travis Nott and Toby Fuchs) has corrupted hair (red and blue numbers). I know this is base game hair because I cheated each Sim to the lot, made them selectable, and went to a mirror and selected "Change Appearance". Both hairs did not have any icons for expansion packs or stuff packs or for being custom content. This has NEVER happened to me before. I have tried Googling this exact problem but can't seem to find my specific one. Did something happen when I installed the base game? Pics of both Sims are attached.
