Daynarr, this not a bug. CI is NOT!!!! a normal project. It is NOT finished when you get enough points, it is finished when
a) You got enough points to finish it
or!
b) you stall an enemy project NO MATTER HOW MUCH POINTS YOU HAVE INVESTED!
You can stall an enemy project with your CI3 in the first turn, in the middle, at the end or don't at all, anytime. It doesn't matter. All you have to do is to spend some points into a project to keep it going.
