I sent in the saved game that is causing this. Figured I'd post here to see if anyone else has come across this.
I have a mining base on an asteroid field. There is an enemy ship underneath it. No idea how it got there. Now every time I click the Turn button I get the *if you attack you declare war* dialog box. Trouble is the ship is not mine. I can make the dialog box go away by clicking No several dozen times. Needless to say this game is over unless I destroy that ship.

If Korath Heavy Fighter M5-6 962 attacks the planet mining base 63 the Crylon Legion will declare war on you. Do you want to attack?
AI is Korath. I'm Crylon. Hence the trouble
