The exploration of the Blight Zone on Silan isn't working (at least for my toon there). I stayed there until it showed "xxx has been saved" three times, but it never updated the achievement window (yes, I did refresh).
Tried killing mobs there too, not sure what else to try to trigger it, waiting until "xxx has been saved" showed up was enough for the other areas.
