I have an existing Sauron, the Dark Lord brawl deck which contains 9 Nazgul cards. As of a recent update, the deck will not allow me to play it and states that "this deck has too many copies of a card." The only card I have multiple copies of other than basic lands is the Nazgul cards as I have exactly 9 in the deck. The card still reads "A deck can have up to 9 cards named Nazgul," but that feature is not registering in the game.
