Perhaps there is not a repeat reward item protection, perhaps there is, but I can confirm it doesn't work. Not only did I receive from the season pass engram a ship I already own, but the one i currently have equipped no less. Is there a way to get a EV engram added back to my account? If not... I guess I get it thats alot of fixes for repeat engram rewards on players. At the least, this is just to let you guys at Bungie know that if there is a repeat reward protection system it is not working.
