I think gimil is getting a lot of unnecessary attention here. The original author wants the map redone. If the original author wanted we would have to pull their map from the site, not just redo it. All the maps we get to play on belong to users who let lack use them through an agreement.
We've had complaints about the inaccuracy of British Isles for a long time. The goal of this revamp from my point of view is to improve the graphics and the accuracy of the map.
If you don't want this map redone pm Nobunaga and look at the topic he made : http://www.conquerclub.com/forum/viewtopic.php?t=35358
You should consider yourself fortunate that Nobunaga still wants his map on the site. He could tell us to pull it and we'd have to do it, no choice.
