Problem resolved.

I have the exact same problem, however with adding gold cards to the steelers for a gold token? It accepted 6 and then stop accepting any other steelers cards after that?

I know I am having the same problem. I did Bucs then tried to do falcons wont let. Worse part is that was supposed to be my completed set to complete my daily objective. Now I am out of luck just like twitch not giving me my Reggie White legend card. So far bad experiences and getting screwed around. Not good but then again when does a game care about its consumers?? And goes out of their way to right a wrong? Dont hold your breath.
