According to the 1.2.0 patch notes, "If you have the quest 'To Fort Virak,' you are now still able to complete it even after you have completed the Fort Virak objective."
Well, I completed the quest "Breaking Fort Virak" and completed the objective without talking to Sergeant Gjorring of the "To Fort Virak" quest first (didn't realize I was supposed to do them in order). But "To Fort Virak" is still in my quest log and the marker for it goes to the middle of the camp where no one I can talk to is at. So how exactly do I complete the quest? AFAIK, I have the latest patch of the game.
