Guild Wars 2

Hi, I Have problem. I am doing HoT story, but I can’t continue. I have speeking with Scout Acan in part 5 (‘’In Their Footsteps’’), but he still plays on the guitar. Can you repair it please?

I got him to talk to me by gliding down right in front of him. If I approached him any other way he wouldn’t talk to me.

I get that his dialogue involves admiring your gliding, but the requirement is silly since you can reach the plateau using other means and from behind too.
