hello mojang staff. I dont know if this a bug or not but I'm anyways .The problem is, everytime minecraft updates all my custom skins/geometry skins are reset meaning that they just turn into the default Steve skin or if you were using custom capes,they would all disappear and leave you with your original skin .When this happens you would have to comepletly reinstall minecraft and do the process of moving your custom skins to the persona folder because minecraft doesn't recognize custom skins as regular skins. This also happens on all versions
