Space Wolve 3 need help at escape after investigate covey at jerusalem

[rocksk]

This mission is where you investigate alex's convoy which went missing near jerusalem.

Mission start well as i enter the blockage system. MSF have the place lock down but a visit to watchman had open a peaceful path.

After picking up greyhair. All MSF turn hostile and start chasing my mothership.

Mission is now to escape back to Jerusalem. After enter jerusalem, conversion state i need to get out of system or dock to change id. but no matter which direction i go, a preset cut scene blow up the mother ship.
And my current 3 fighters cannot kill off 3 ways of attacker.

This is totally lame way to stop me from escaping.
