The advice of going through portals from Lions Arch worked perfectly.
Some quick info, hopefully it helps out people:
- I have all Hearts, Vistas, POIs, Waypoints, Skillpoints.
- The only dungeon I did was Arah for story completion at 80.
- In-game it says 100% World completion.
- Login screen says 98% and the World Icon when hovered says 97%.
In the end, going from Lions Arch to Hoelbrak didn’t work. Then I tried Black Citadel and immediately got the rewards.
Hope this helps out and GL!
