We are having problems with a sea battle. The game seems to have frozen at the pirate stronghold. The timer went to zero seconds in the land battle phase, and we never boarded the ship for the cannon shootout. We've been stuck on the stronghold for about 50 minutes, and the problem doesn't seem to be going away. All of our mounts/buffs are expiring, and we can't even quit out of the battle to get back to the normal game. Please help!
