I was at rank 79.7, and won on a single snap. Got the win screen and everything. I went to the rank track to unlock the avatar reward, and it gave an error when trying to do so. I then relaunched the game only to find my rank moved to 79.3 and the collection track never indicating I broke 80. The game appears to have reverted my previous win to a loss, taxing me 4 cubes.
