Please have a look at #27184
I think that carmoil and sunsethomie are the same player. They often move at the same time.
e.g. in Round 6 sunsethome fortfied_all_ his units to support camoil. Europe is now without any defense.
--edit at the end of his turn camoil fortified his units back to europe...
I can't believe that they only use the game chat to communicate...
