I'll make it short and simple,
First of all you had to have to flying path there.
- Fly from Ashran or any other place in dreanor to your garrison.
- You will get stuck in the air above your garrison if you don't go back to any place and fly back to the garrison untill your stuck above your garrison with the flying grphy getting error msg instance not found.
- Logout ( Niote you will log off instantly ) Log back instantly and then the flying mount will change into the shoplike mount forgot the name.
- You will then fly safely in your own phase garrison without d/c lag.
