Same bug here:
Quest mode, finished an adventure successfully, Merisiel (Rogue) levels up to 9 and her Spell card appears off screen (just above the viewable area, by the look of the aura). First my Wizard gets his benefits from going level 1 to 4, and I click through those.
Then Merisiel gets her bonus card, and it shoots up to the top of the screen, so I can't tap on it to confirm and move on.
