You're not alone. I've tried creating copies for different outfits so i havn't got to mess with the HUD but I can't get layers to stay hidden, when logging back in either. When I load the HUD up, it's showing they are hidden but aren't. It's infuriating having to load the HUD up all the time and reset them. Maybe it is something we are both doing wrong but i doubt it. I think it's just a buggy product that I'm going to stop using.
