I have a really bad problem here!, a mission has appears, and this one is impossible to achive, this looks like a regular police station detroy mission, but if you look carrefuly, no team is specify. I tried destroing both police station and didin't work, Also I destroyed my own station , and nothing, the mission is imposible to realize!!

I loaded a previous state of a saved game, and the missions appears again.

That is weird. In all the play throughs I've had with both my CD and GOG version of this game on 5 different computers, I have never encountered this bug before.

Are you fairly new to the game? Did you see anything like this happen before?
