Just look at my recent game history,  the only time i have ever sene and invalid gamestate at the exct citadel deathsi when playing against py4eek and he is losing.  Then i kick him from a game i am hosting when he is on my team,  and i ask him why he does it.  He says because I can.  Do not play with py4eek my win was hard won and he still invaldiated it and left a horrible taste in my mouth.  Noone who is really good at this games cares about win %  but it just makes u mad when someone does that.
