Wrong coordinates in quest: Salvation

Licancura - Archosaur

First time I do this so I hope I'm doing it right.

In the quest "Salvation", one part is "Trebuchet Design", when the Elder sent to talk with blacksmith Tang in north Acrhosaur.

I used the autopath while flying and I ended up in the river next to Starway to Heaven, coordinates 400 550.

I did this low level quest with other characters time ago, and I believe the coordinates were right then.

Thx
