My game was going well until I encountered two bugs, one where an army vanishes into thin air, and the other where even though New York is held by Clinton, some light inf. and a cannon, it says it's under US control and I can click on them to move them away.
I have a save for the latter, and if it will let you go back two or three turns, it will show the former.
Kinda kills this game for me, as I'm not sure if everything else is going to be right. But I hope this can be explained or fixed so I can get back to being outsmarted by Washington.
