On the second step of the quest, it requires what the description reads as 20 Super final blows, however the icon shows a fusion rifle and, while I was somehow able to get 6/20 in progress, none of those 2 listed progression options worked in my 2 previous iron banner games. I'm fortunate enough to have this happen to my side characters and not my main character, but it still sucks to miss out on the armour's the event offers due to mechanical errors.
