Roster Quest - Nose for News

Roster Quest - Nose for News -
Quest progression is broken for me. Even though I am standing where I should, in front of the water fall just in front of the grass in the water and placing the indicator in the water just in front of my NPC using the Magick Flow Detector as directed the next point in the path which is the second point just prior to finding the hidden NPC will not register. I tried using the Magick Flow Detector in every location in the area.
I know it works for other players because I watched them come and finish their quest. Any help?

i have same problem for 3 days now i still can’t get it tried youtube videos and still no luck.
