I was happily doing a quest mode adventure, got a victory, my characters got experience and some of them were supposed to get a spell as a level up reward. Now, whenever I try to claim the reward the animation of a new card starts, then gets stuck before the card appears (the glow is there). I've tried force quitting the app, uninstalling and reinstalling it, doing a story mode adventure, pressing "continue" on all the different characters involved in the adventure. Nothing helps for quest mode. I always get back to the victory flow, where I get stuck on the first quest reward (see imgur album).
Device is an iPad 3, os is iOS 9.3.4.
