I've got an odd problem, forgive me if it's been mentioned before.
On the mission where I have to escort the Brakiri cruiser to a meeting with the shadows, and everything goes south, for some reason this mission is unwinnable.
Right around the time I finish dealing with the second wave of shadow fighters, the Harvester just dies. It goes from 100 percent hull integrity to a flaming cloud of expanding debris in about five seconds. I'm not sure if the Shadow cruiser hit it with it's main beam weapon or what.
I tried taking out the shadow warship's main beam, but it's got an invincibility tag.
