Me and a another coach just had a game stuck in the event before turn 9. It was a Rock event, targeting a goblin (from goblins team) into a KO. The timer to decide if the coach use the Apothicary or not on this KO goes to its end, and after that nothing happens anymore.
Basicly the turn 9 never begin.
Here is a video I recorded with my twitch channel. After the issue both the opponent coach and I forced quit the game and came back, making the match displaying the last actions again. So you can see what happened just before the recording since it is the same behavior.
