Arena KEEPS crashing

I thought that too, but I've had it crash in the Penny Pursuit as well as Arena using the Electric Peashooter and Lightning Reed.  I originally thought it was the snow pea as well as it piled up the zombies and created too many "objects" and ran it out of memory.  However, it just crashed on me with hardly any zombies on the board at all.  Perhaps the next wave of zombies created too many objects for it to handle.  It just smacks of a memory leak as it'll happen to me with a minute and a half in an arena, or a few seconds left (a true rage inducing situation especially when you are winning).  I can say this, it makes me not want to spend any money on the game.  I don't mind spending money on a game, but I certainly wouldn't buy gauntlets at this point as that's pretty much going to result in no benefit for your cash.
