Issue with transportation system with this latest beta (working good on the last HB Release and i hope you dont do a release from this beta until you are able fix it).
Example on how to test and debug it: Fire up the DK starting quests, let it play for like 4 min, when it needs to go down from the starting place on the sky to the ground, instead of taking the flight master, it will try to run like a crazy to the waypoint that is way below on the ground without trying to do the automated transportation system.
I got the same issue, when it reached the quest where it needed to go from the ground to that sky place, which shows that it is not a questing related issue but rather something broken with the navigation system.
Here is what's on Kick's questing profile :
<!-- Report To Scourge Commander Thalanor -
Report To Scourge Commander Thalanor - Quest - World of Warcraft -->
<PickUp QuestName="Report To Scourge Commander Thalanor" QuestId="12850" GiverName="Highlord Darion Mograine" GiverId="28444" />
<TurnIn QuestName="Report To Scourge Commander Thalanor" QuestId="12850" TurnInName="Scourge Commander Thalanor" TurnInId="28510" />
As you see there is no questing behavior required or anything but to take the quest from an NPC "Highlord Darion Mograine" on the sky tower, and to bring it to the other NPC on the ground "Scourge Commander Thalanor".
