So I started my first game, and everything ran smoothly (though I noticed the river in the ocean bug mentioned elsewhere) until I tried to start my second war. I moved my unit into their territory and got the "Do you want to declare war?" popup. I clicked yes. It popped up again. I repeated that for a few more times, then clicked no and it went away. I tried again the next turn with the same result.

I have no screenshot because the game wouldn't maximize again after alt+tabbing out to open something to capture the screen, not that a screenshot would show much.
