Thanks for the answer.
I was thinking to make it like costume weapon to solve some bug (not letting equip costume_armor without armor, and unequip costume_armor if a normal armor equipped) but it'll be shit for players i think, it's going to the countersink now
I have a bug:
Equip an armor and a costume, then hide the costume, now unequip the armor, and still see the armor instead of the basic character layout.
This is just for me or it's a common issue with this system?
