Yes, I think it's the nude hat bug but It's a bit of a weird one because he's a mermaid, the hat, a base game do rag that I didn't add to any of his outfits in CAS only shows up when he's in the shower, he doesn't wear it when he's in the bath or swimming as he's in his mer form in those instances. He doesn't have it on any of his outfit categories in CAS including his mer form, he's a science baby from a multi generation mermaid mother, he doesn't have a father so his mer form is completely different from his everyday sim form, different eyes, nose, mouth, face shape, body shape etc. It's like the hat is hidden/invisible until he takes a shower. On a side note he is the only science baby, his three brothers and one sister are natural born from two mermaid parents so I don't know if that has something to do with him being the only one afflicted with the hat bug? That's why I was wondering if he's stuck with the hat forever even if I did split him from the household because his existence is a little convoluted 😅 would uploading him to the gallery to mod reset him still work with him??
