you must've disturbed the ghosts
here what worked for me
take your group and kill all the ghosts first, kill the major specture on top of the bridge, and go the back to talk to dojo again. (don't save your game)
THEN go out alone to try to lower the bridge again (make sure not to disturb the specture or the specture's not there)
BTW WELCOME TO THE W&W forum!
