The card spawns and then moves up off the screen, or if I tap it the card quickly moves up and does the reveal animation, but I can only see the very bottom of the animation. Exiting the game and restarting puts me back at the reward screen with the same result. I've tried story mode with no luck.
I can't find any way to progress since the only way to bypass the screen is to tap the revealed card. Screenshot: http://i.imgur.com/G14z20p.jpg
