I've paid real money for this game, and get very frustrated when such things happen. The last shot was done with Eddie the bird, which killed 5 pigs resulting into victory, but all controls just disappear and the victory screen does not show. The game is not frozen - birds and pigs have their idle animation rendered. After 2 minutes of waiting still nothing happens. Restarting the game app results in a lost battle - lost trophies, no dungeon key & coin rewards, lost ticket to a PvP game. I had no internet connectivity troubles.
