When i entered the store and clicked the tankfest tab, i saw the gate guardian skins for the FV 4005. I have these already, but it was going to allow me to purchase both the ww2 & cold war skin shen i already owned them. Look at the screen shots attached. On the cold war skin, in the screen shot it doesn't say i own it, but i do and have it equiped on the tank already.
