On iOS for iPad, my fighter leveled up to 29 and got a spell card as a reward. Whenever I try to click the card to claim it, it just becomes a glowing halo and the game locks and I can't do anything. Forcing a close and reopening the app just leads to the same thing happening.

 

Can't continue quest mode ever, now, as every time I go into it I just get the "end" of my previous one where I level up.
