Citadel Gone After Fighting Conqueror

After fighting Drox the Warlord his watch stone didn't drop. Then, I got the opportunity to fight Sirius. I fought and died to Sirius, and after that I noticed the citadel on the top left had disappeared. As you can see I have awakener lvl 5, and the citadel that disappeared had four watch stones in it.

I see what happened here now. My citadel moved locations, and is now under leyline. The problem was that the highlight map is covering the leyline citadel. Not a bug, but I would suggest an interface adjustment here to avoid confusion.
