I haven't played in a long time, and logging back in I decided to try the new zone tracker to see if there's any zones I haven't completed. Clicking the top-most location on the map, Alik'r Desert, and it tells me I'm missing a zone story quest "In Search Of The Ash'abah" and tells me to talk to King Fahara'jad.
The King's not standing at the map marker. When I went into the dungeon where he is standing, he has no quests for me. Doing some research, all this quest is is pointing me to another quest hub (Morwha's Bounty) which is all completed. So there's apparently no way I can possibly "complete" this zone by the standards of the Zone Guide. It looks like I did thing in the "wrong order" (years and years ago when I first did this area) and as a result am stuck now?
The *really* annoying part is there also doesn't seem to be any way to tell it "hey skip this thing, do the next thing instead". So until this bug is fixed, the Zone Guide is useless in Alik'r Desert for me.
