I wholeheartedly agree.
Strangely, the issues the entrenchment/diplomacy started occurring much more frequently after this last patch, so that would seem to indicate that that is where the problem lies. I still have not actually been able to even get near to the end of a multiplayer game of diplomacy (all of the times, starting sins up fresh). I will try to get on this weekend with a friend and download the desync kit so that we can try to get to the bottom of this. I would like to suggest that others try to do the same. It is kind of frustrating that such an awesome game as diplomacy has all the pacts and stuff, but I can't use them with other people.
