Blizz can you please fix your buggy ash game? I have literally had to redo the Arthas lorewalking story 3 times due to buggy quests and Cho being about as helpful as a chocolate kettle, i thought i had finished it but had full bags, so went to sell the junk and when i came back it made me start the whole thing again, now its bugged again on Icecrown Citadels stairs where you ascend as the Lich King, it wont talk to King Terenas anymore and now im stuck for the 4th time!
It’s still broken, I had to leave because it said I needed TWW, now that I’ve wasted that money I come back to do it and I still can’t do it.
Just got really pissed off about this. Managed to get my wife to play wow and found out that these lorewalking quests would be a nice way to show some key moments from wow history. This quest line is quite long, but we had a somewhat good flow and got to the last part where player would control the Lich King. Alas, only my game advanced to the this part but my wife’s game bugged where Arthas is behind the collapsed tunnel.
My wife didn’t have The War Within because we weren’t sure if we would really continue with the story at least for now. So she got the error message that this part of the story requires War Within. Not sure why this could have anything to do with War Within 
and bought the expansion to my wife, but to no avail as it now says that instance is not found (feel a bit being robbed here). Have tried everything, talking to Cho, restarted game, done the Jaina part couple of times, stopped and continued the story several times, but always: Instance not found. There is no way my wife (or tbh anyone would) like play the whole story again…if it really even would change anything.
It seems that people are facing lots of problems around this quest (us and eu forums). How would this kind of iconic and very long story quest through the quality assurance?
