Spaceship parts and espionage

[Kemal]

Perhaps some of the more experienced civ4 players can help with this?

After a long break from Civ4 I started another BTS game recently, and I'm now in the end-phase of the game, in the process of completing the spaceship.

There's two continents. I own a large part of my own continent, and have a small foothold on the other consisting of a few american cities, including former capital washington. There's no centre of government there though.

So how come that when on the turn I finish my SS-cockpit in one of my cities [u]right next to Babylon</u>, on my own continent, I get the message "an SS-cockpit has been destroyed [u]in Washington</u> by enemy infiltrators"? That's on an entirely different continent and has nothing to do with spaceship production whatsoever!

I did get the "Kemal has completed SS-cockpit", "Mira has added SS-cockpit to the space ship" messages and the add button for the cockpit on the space screen, but I still have to build a new one.

Totally lame and boring, since I had timed the parts to perfection and now it takes 7 more turns to complete the game. I would have accepted it if they have managed to sabotage in my own cities but like this...?
