I've tried the Halloween Tower Dungeon in Ravenwood four times; twice alone and twice with others, and all four times after I get through the fourth level (I think it's the fourth; the one after the wisps) the gate to the next level goes halfway up, and then quickly close again. Then nothing. Others players have also had this happen. Is there a glitch?
I'm having the same problem on the last tower, defeated the first two levels, and waited for gate to open and nothing. I even went out of tower, redid it completly and still can't get to the final level.
