Nostalrius Begins - Quality wow vanilla realm (1.12)

The last few days, my character is flying in mountains/terrain when I log on. Could you fix this? It flies randomly around for up to 5 minutes, and sometimes it flies from SW / IF and to other places, so I have to port back (mage).. Character name: Dhomden

Let me know if you need more information, thanks

Same problem here. When I log on I'm on a gryphon as if traveling by flightpath, but usually the gryphon is just flying around seemingly at random, some times below ground level for several minutes. Makes no sense.

Same here.
Was logged out next to one of the Auction Houses in Undercity. When I logged back in several hours later, I instanly get put on a Wyvern that flys me first to Hinterlands, then Ironforge before it finally dropped me off in the sea west of Menethil Harbour and I got ported to a nearby graveyard. Afterwards I was running at atleaste 200% of normal speed.

Same problem here.
I'm flying somewhere north. My location says "city".
I can be summonned by a warlock and it works until I log out again.
Then again I'm flying and can't move.
Please, let me know if you can help me.
Thanks!
My in-game toon is Visionnaire
