A couple of weeks ago, the option to buy card styles by clicking on the cards in my collection disappeared. I can still "craft" cards just fine, but I can't buy alternate cart art styles--except for the daily deals at the store.

Also, when I play Midweek Magic, I don't get prizes--there is just an empty screen at the center where the prize graphic should appear--for either both the first and second wins or just the second win. The third win gets me an alternate card art style still, however.
