I was playing Vulture in the arena today. Mine is a 3 star, maxed out, max sig Vulture. I didn't notice this at first, but while fighting I realized that there were two Decoy Passives on him. Now as far as I know, that ability isn't supposed to stack, and as a matter of fact, it didn't. I tried to get another one, but I didn't, and when I got hit, it removed one Decoy, but one just remained, and no amount of getting hit would remove it. It just stayed as it was. Kabam, bug alert. Please fix this, because it is very misleading.
