I'm playing the F.F.B. plug-in, and when I complete a mission for either the Rebels, of the Confeds about searching the Sepens Nebula for planets that are under control by the Red Aliens, the mission repeats itself. I accept the mission for the Confeds on Mars, and Palshife for the Rebels. Why does the same mission repeat?
