TBC quest "A Visit With The Ancestors" - Unable to complete.

[RotS 0]

I can`t complete this quest fron Nagrand. I`ve been roaming endlessly on the objective locations. To be precise I manage to randomly step on the exact location of 2 out of 4 of the objectives. 

Quest objective locations seem different from what Wowhead or quest helpers suggest. So i started roaming the area and in Sunspring Post location and Laughing Skull location i managed after a while to step on the "right spot" which to me seemed completely out of logic and weird. Still unable to find the other 2 (Garadar and Bleeding Hollow).

I also asked around and other players apparently didn`t have problems completing this quest.
