I am also stuck on 12/13 for the achievement. I have done every map twice over the past 4 days. I have DCd on a few maps and inlue of the information provided, have always come back and closed more portals in the zone and killed champs-not pirates or flame but clockwork champs. I made a zone list and completed each of the 13 zones concentrating on portal closures (at least 4-5 per map) and killing clockwork champs. Not sure as to what the counting issue is, but I agree that the achievement should have had a zone list in black when successfully counted it should turn green or have non counted areas in red. this would greatly reduce the amount of frustration for players who are trying (like me) to find the one zone for the achievement-a needle in a haystack so to speak. Home world is Dragonbrand and many of the zones were completed in overflow to date. I always stay till the bitter end of the long event. hope you guys can figure this out. DS
