When I hit this waypoint and take down the first 4 Kilrathi ships; there should be another wave of fighters that jump in. That is not happening and it's causing me to fail the mission. Any thoughts on this?

I gave up with this damn game to be honest. Had the Blackmane bugged mission that could not be completed. The only thing I could do was travel to the Victory manually, which took about ten minutes. Next thing I know I'm in the Proxima system heading towards the unwinnable path. Not fun at all.
