Guild Wars 2

im trying to complete finally the personal story to get the achivments from it.

and ive came over a bug in the “Ships of the Line” quest.
ive heard that this was fixed but ive seen that this is bugged for me.
im trying to revive Elli in the water, but Zott wont follow me into the green circle on the map.
making the rescue of the crew impossible.

ive tried swimming around to trigger the script, but none has been accomplished.

does anyone know anything that might work?, or is this the end of the personal story for me?..

Update:
ive managed to advance farther, reviving Elli and returning to the ship.
all i did it restarting the whole mission again, relogging in order to get out of the bugged mission and starting it all over again.
worked perfectly the 2nd time.
