same here. i take the quest, join an lfg, am automatically offered the quest again and then its no longer in my quest log. and i had the same experience with asking party members if they had similar issues and not a peep from them.
i really think the auto offer may be an issue. the game may be removing the quest from the quest log so it can offer the quest to the player at the start of the instance.
I am also experiencing this as well. I know the 20th event is ending soon but this is kinda annoying that I canāt get it done.
The only reason I donāt think this is whatās causing it is that the quest is reportedly wiping after loading screens. Iāve observed, having my log open after hitting a loading screen, the quest WILL be there for a moment, but shortly after everything around me loads in completely it vanishes, even if I had partial credit from the auto-offer being obtained inside a dungeon.
It seems to have something to do with the script thatās run after you load in completely from any loading screen.
Same issue any update from Blizz on this?
