You get this quest from Mordant Grimsby at Swamplight Manor . I play horde but he seems to think I am helping the alliance.. little does he know Hehehe

Anywho, when I get the quest I am supposed to gather information from 10 Risen Husks or Risen Spirits at Witch Hill.  Witch Hill is at 56,25 (approx).  The problem is when I am at 56,25 the arrow is telling me I need to go 2796 yards south.  I figure this quest  just slipped though the cracks somewhere. When I was done with the quest it did correctly point me back to the NPC I needed to see to complete the quest.

Thank you
