If you had multiple skinless reds before 1.2, you only got one red skin after patch 1.2 went live. I had two red recruit’s chopping sticks and got one illusion that I applied to one of the chopping sticks.
Since the illusion, Gilded Glory in that case, is one use only, I still got one skinless red halberd.
From what I read at reddit, the same applies to saltz’s red volley crossbow.
