Guild Wars 2

I was trying to finish the map Bloodtide Coast and was not able to get the point of interest at the sorrowful sound.
So I was looking for guides on how to get there and watched like 5 different on youtube.
Each one of them started by destroying a lamp post. And that’s where I can’t get further because I cannot attack any of these lamp post. Only 1 lamp post has a health bar and it is not red, it’s yellow.
I’ve destroyed all lightning turrets and checked out all data recorders and nothing changed. All I can do there is destroying turrets.

Has the puzzle been changed or what am I doing wrong?

That faint little square you see on the island is not a point of interest. I completed that map with two different characters before I even found that puzzle. So if you a only worried about completing the map move on. If you are trying to complete the puzzle, it is difficult to figure out without the help of google.

same problem here, is it broken? cant attac the lamps and there is no panel to interact with
