Bug description:
I'm doing the DK mount class quest right now, the quests name is "Frozen Memories" (questID: 46720) where I talked to Amal'thazad to take the quest, I took the teleporting disc beside him to get teleported to the roof of the DK order hall where the Lich King came as a hologram and talked about a vision, then the next step was to go to Icecrown to witness his vision.
I went to Icecrown on the destination I found that small ice patch where I stood at it and witnessed the vision (where undeads were running towards a sleeping dragon) but then vision ends and the quests doesn't get completed, I checked the youtube, wowhead, and freakz guides all say its supposed to be complete at that point but doesn't count as complete, and the worst part is I cant even abandon the quest to take it again, every time I abandon nothing happens and the quest stays as it is. I tried relogging and reloading and everything (deleted cache folders even) nothing works.

From the video you can see that he traveled to the place and once the third dialogue begins the quest is completed, yet in the images u can see from the time (on the bottom left of the screen) that the pictures where sequential and even after the fourth dialogue ended nothing the quest is still unfinished.
p.s: the youtube video is the exact same link posted in Freakz database for the quest so I dont get the "check the guides" reply cuze I already did gizillion times over and over

This last link is to prove that I couldn't even abandon the quest so I can retake it and redo it again. but the quest doesn't get abandoned.

Seems like you solved it, you just needed to relog so the scene can start again.
