Locks up on level 9, 3 minutes in – Zeus vs Monster: Fun Math Game Review

My first grader loves the first 3 minutes of this game. Sadly, on level 9, an opponent appears and walks across the screen but there is no Zeus and no math problem, so when the opponent reaches the other end of the screen the game locks up. Tried on both iPhone 4 and 5, tried deleting and reinstalling. Hopefully it will get updated so I can change this to the 5 stars it deserves for a non-crashing version. The other reviewers are employees of the developer. Google it.
