Perhaps it couldn't handle so much treachery in one turn?
Seriously, no problem (ethically, that is) with your attack since all we had was an understanding at best. If I were in your shoes I would do the same. You let me take a beating from Ctis on the BF and with his DomKill/disease for a bunch of turns, and as soon as you see the tide turning in my direction - BAM! Masterful.
The next few turns will tell the tale, maybe we won't make it to 2011 after all!

PS
After the game is over perhaps you can tell me how Polydamus doubled his HP to 440?
