Hi, I've been playing BFA for a while and I have a DK currently at level 101. Recently I started the quests for Warlords Of Draenor but after completing the first questline I reached a mission in which I had to ride with Durotan and Thrall (among others) up a hill but after reaching the destination, everyone disappears and I can't complete the quest so I had to abandon that zone.
I was told to go to Dalaran and take a quest from Khadgar but I went there and he doesn't have any quests to offer and I've also tried to complete other quests, for instance one outside Orgrimmar which is to prepare (eat food, prepare armor...) but that one didn't work.
I'm stuck, where else can I keep leveling up?
