There are a few bugs causing stronghold to award wins to the wrong team and/or end the game early.
1) the game went into overtime, the enemies had more points, and when we finished their lord they were declared the winners
2) our lord was downed, i used signet of mercy to revive him but as soon as he was revived the game counted it as him being killed even though he was alive (and he continued to have the downed symbol floating above him)
