ok, this was pointed out to me by a friend not in my guild. We have 50 slots to collect our cards. When we get to max no more cards will drop. But, if you buy cards it will add those cards to your roster regardless of your collection being maxed at 50. One of the big spenders has this going on now. They have 51 cards currently showing in their collection.
Is this an exploit, or an error in the card collecting programming?
