@AquaGamer1212 Cupid just explained it to me in the previous posts. The texture map is full, and having the textures of various different clothes / accessoires in the same spot might cause issues, as seen with some CC that becomes weirdly textured when used together with some other stuff. For more categories to be added, the map would have to be expanded, and that's probably too much work for too little gain.
I still don't understand perfectly how this works, as I've sometimes managed to trick the system with my own CC, but maybe it's a hit-and-miss thing and prone to bugs. And if there's one thing we don't need more of in this game, it's bugs. Sucks, but... eh. :/
