Guild Wars 2

When I get to the part that tells you to fire trebuchets against the ghost ship, no matter where I point the trebuchet it gives me a message “you cannot fire the weapon in that direction” when I try to fire. Anyone else have this problem or am I doing something wrong?

I got that message once too and thought it was bugged. When I did the mission again I found that I wasn’t holding the fire button long enough. So that is most likely your problem.

Thought I tried that. Even left, came back and tried again. No luck. Finally found that you can just swim over and attack the boat, it has low hp. Just did that and got past the event.
