Most all of the quests for ghost of karesh do not work. Quest npc’s just aren’t there, quest progress stuck not being able go from 4 to 5 kills even if you have killed 100. The warrant quest is broken for alts no matter if you skip to the reshii wrap or not. I don’t understand why Blizzard keeps doing this to us. We pay for this game every month and they can’t even do is the courtesy of testing their own game. Getting so very tired of playing this broken mess. But it is one of the only games my girlfriend and I have to play, before y’all go off saying “pLay SoMethInG elSe”
While I am not familiar with that specific quest line, I suspect they aren’t broken, but you are missing some prerequisite or are on a conflicting quest. While many of the quests made sense when they launched, trying to do quests that were a few tiers back often becomes challenging since you will have skipped some prerequisite.
Here is a link post, from someone that had a similar problem to yours, hope it can get you moving in the right direction.
