Lion's Arch Map Bug?
Though I agree this is a bug, it is very minor and I think on purpose. They also didn’t change the NPC’s dialogues in the former lighthouse, and they are only there after some extensive climbing. I think they are waiting for the workers to have build the new lighthouse (read desiginers to make the drawings final) before changing the map.
