As the title says, but with more steps. The “Dragonflight” weekly and the queue is still up, but they disabled the ability to turn in the quest-item quest and the vendor/raid-queue NPCs in Dalaran (Northrend) are gone. Come the * on and fix!
Edit: I only later realized the actual Turbulent Timeways buff and event is indeed also gone. Despite what the calendar and common sense says. 
Hah, by the time they realise this the event will actually be over.
Hence me making a rare forum post. sigh
2 days too early actually. The vendor usually stays through Wednesday as a chance to buy items even after the event is over.
I see. Well that’s 500 badges on every character and the raid quest-box that we can’t get. The calendar is wrong and nothing was posted about a change. Equals big huge fail.
Well that sucks, was going to do the raid quest today
Yeah. I was starting “this night”, continuing “tomorrow”, and noticed the quest dropped from my log at 04:00 on my main. Which isn’t even the daily reset. It’s when Turbulent Timeways ends tomorrow night , but that still isn’t when this should go away as the calendar says TW is going away at 05:00. Despite the new daily reset after winter-time switch being 05:00, but that still works TO ME! Quite stopid.
they use USA/NA timers for EU realms! omg
Except when it all went poof it was about 20:00 (8pm and all the other timezones!) in NA.
Awesome… so much for last minute cramming. 
Timewalking is still there for me.
The dungeons are, but the NPCs were gone last time I checked so you can’t turn in related quests, buy items or do the raid.
Ah, so specifically raid related NPC’s .
I was going to say I’ve just done a time walking and got the mount and achieve for doing it for 5 weeks.
Yeah its not just raid NPC, the badge vendor is gone.
Hmm… I am sure I have read a thread similar to this situation months ago about timewalking ending at 4am. So perhaps it is as intended, annoying as it may be.
. . . . . wrong day . . . . .
No, I am pretty sure the situation was the same. A tuesday at 4am. In fact I am sure I remember being cross at the same thing. If it is a bug, it has been ongoing for a while.
Not sure about the raid NPC, but the vendor usually stays a day after the event to give people a chance to buy stuff. The event itself is still up, you can queue for the dungeons, but the NPCs in Dalaran are gone.
Oh yeh, they’re gone.
Noob Blizz!
honestly, I don’t know why the vendors aren’t permanent. I missed 3 hand ins last week.
report in game bug now so they fix it
