This is an old thread I found with Google but I am having the same problem and it's frustrating.
I actually managed to keep the Frigate alive and the Glory just left on it's own. Then the Frigate goes and docks with the asteroid base, the Combat Utility Vehicle (Reload) and then trys to dock with itself! I I brought the hull of the Frigate down to 50% and it jumps out, but the shuttles get stuck flying in circles. The Grey Wolf never arrives.
