Guild Wars 2

I reached 100% map completion awhile ago, and when I open the map up all tasks, waypoints, POI’s, skillpoints, vista’s and overall percentage are complete. But when I open my Achievements under Explorer it says Krytan Explorer 175/175 areas, Orr Explorer 59/60 areas, Maguuma Explorer 162/166 areas, Shiverpeak Explorer 170/174 areas, and Ascalon Explorer 176/176 areas. Any help?

there are areas without any poi or so, mostly hidden in a cave or something and very often they lead to a jumping puzzle. you must revisit these areas and search on the sides for hidden entrances. on the map you can often see them because of themisty look on some places. hope this can help you

Yeah I have areas that are unexplored, but they pop up as I have visited some of the hidden JPs around the world.

The POI consist of both those orange boxes on the map AND area names. Perhaps, you are missing area names. Check this out – http://wiki.guildwars2.com/wiki/User_talk:Bluestone/Explorer

If, however, all of the names on your map appear in that list, then most likely you need to revisit WvW.
