Guild Wars 2

A while back I had 100% map completion on my first 80. Now it seems that there were two altered/new waypoints and I found one of them.

The one I found was in Cursed Shore and it was [Shipwreck Rock Waypoint].
I haven’t found the other one and I’ve been looking hard for it.
Would anyone know which one that would be?

They added them to areas with contested waypoints. These new waypoints can not be contested, thus giving us a point of entry into the map. You should be able to find the missing one by hovering over the name of the map, like “Cursed Shore” when the map is open. This shows a tooltip that shows the percentage completed of the map and what is completed.
