I'm lvl 18, I tried entering the south dark zone, Near the gate a quest start which make me use the computer, then send me in the sewer near the entrance.
I went down and got stuck in the sewer, can't open the door to exit the sewer and can't climb back the wall(too high) to exit. Can't teleport either.
The only way to exit is to log off and log in again.
Tried four times, but was the same each time.
