Ok so I just got this game. Playing through the very first campaign (Terran vs Dread Lords) just to get a feel for everything and REALLY enjoying it. However, one planet I captured I just can't seem to build any ships. The military production of that planet is (0) - even when focused. I have several traditional factories on the planet and my faction's military spending is set to 75%. (I also have a starport, in case you're wondering.) It has a population of 8bn - but no matter what ship I put in the build queue the estimated build time = never. What am I missing?
