Hi there! Same thing happened to me too on my iPad Air, iOS 9.3.1. Not playing with permadeath or pass and play. Completed normal Quest; Merisiel, Ezren, and Valeros leveled up to level 5 while Kyra leveled up to level 3. Kyra got her card reward no problems but when either Merisiel, Ezren, or Valeros tried to get their random ally card reward, it would shoot up above the screen and is not collectible. Other characters not selectable. Tried quitting and restarting the app but still happening. Tried restarting iPad but didn't work as well. Can't get past the rewards screen so kinda stuck not able to do new quests.
