i realize this is an old post however Mr Hinrich has hit upon the correct answer with his question.
this situation happens to me from time to time. if you are concerned about a perfect score then you should end the game early and re-play it from the beginning. if you want to successfully complete the mission and move on, then do just that. i havent played in quite a while however i believe that if you kill at least one Kilo and discover all of the mines, you should be allowed to continue.
good luck.
