Guild Wars 2

So I am on a little island, where you see a bunch of Brackish Skale, in between Viathan’s Arm and Viathan Lake and the waypoint for Vian’s waypoint. There is a undiscovered point of interest, and when I get right on the exact spot it shows on the map I don’t get the credit for visiting it, or being there. I have been swimming around the area trying to see if there is a underwater cavern and haven’t found one. Is this point of interest not working? See attached screen shot

That is a special hidden one. It is working fine. The entrance is near the heart to the southwslest. I’ll let you figure out the rest from there. (Hint: bring your aquabreather)

this one took me the longest of all the pois when the game was new. Was awesome.

OH thanks for the reply, I will keep searching then!
