I can confirm, that I see different IP addresses for the Kourna maps now, and can't see the above one. Interestingly, earlier this afternoon I was able to do this quest with a commander whose name I unfortunately forgot. He rallied enough people to force a new map (that eventually got closed and the bugged one remained) and this is not a small feat, thus a huge thanks to him in the name of others too. However, it seems that Anet did reset the map.
