Yea i know of issue in a couple of profiles hb isnt finding the ground point proper mac. But in the log files it will look like
[09:37:19.104 D] Could not generate path from {4278.437, 5147.213, 56.51206} to {4316.808, 5155.46, 82.00126} on map Draenor (Phase: FWHordeGarrisonLeve2new) (time used: 0 milliseconds) @ FindEndPoly

have a couple of idea's on how to get it fixed on the fly but need to get it tested.
as previously stated fri/saturday its hard for me to get any real work done. because i work 16 hours each day

but tomarow will be able to get at it again.
