In Fable III in the post-game DLC "Traitor's Keep" during the quest to find Whitchcraft Mary ("Traitor's Keep: The Menagerie") the second room in the mansion with hobbes does not trigger correctly. There is supposed to be an enemy encounter after a brief animation, but it does not trigger. I can't interact or harm anything in the room and can't leave the island until the quest is over.
Is there any fix, way to force the event or way to leave the island?
