an Original Path through time is to do 5 timewalking dungeons and is given to you by Bobadormu at the world event area in Tanaris. My frost mage got the quest, queued and did a timewalking classic and when the dungeon was over, i no longer had the quest and it was available again from Bobadormu. So I got the quest from him and logged out. Log back in and i no longer have the quest. I select it from him again, log out, quit game, relaunch log back in and i no longer have it.
I then disabled all addons with same effect.
I then ran my hunter over and got the quest logged out, logged back in and he still had it…normal behavior. I got my holy priest and that one was fine too…i accepted and dropped quests and got it again and it would not drop for those two.
I log my mage back on, get the quest, log out and back in and its dropped.
I guess blizzard wont help with in game tickets anymore, it just directed me to ask the forums.
