I was in the verses on Arctic. I had a 5 + game win streak going. I can't remember the exact level anymore, but it's the one with the catapult. My opponent launched off the Catapult, and when he landed, he cratered in the ground and froze. The game totally froze up. I had to force close the game. And when I came back, my win streak was gone and my ATV was no longer available as if I'd raced and lost.
