I enter the game, play one match, then I leave to get the rewards. When I try to enter in another battle, it stucs in the globe screen, forcing me to refresh the page...and all the tasks that I've earned are back, as if I didn't end it.
Tryed in two different connections, and two different navigators (chrome and ie).

Happens to me too. I must have finished the stick to your guns with the sheep about 4 times now :p It keeps rolling back after the game freezes.
