Hey so the other day I was doing Corta's End and we were at the part were only one person can cross the bridge. 5 of us made it across are last person was having trouble killing the sword bearer but when he did our side got over run and the bridge dropped he could not cross...the sword disappeared. We thought all was lost but we decided to try again we continued killing the 2 ogers that spawned while dodging the gatekeeper (no one was forming the bridge) All of sudden I got radiant energy and the door opened to our suprise we continued forward but we left our friend on the other side and continued. After a little he ran up behind me exclaiming the bridge had formed on its own for him to cross and he didn't have to have a sword. I believe it has something to do with the ogers shortly after killing them we won that stage. Thought I'd share this with the community :)
