@ Goober5000:
Just tested your mission, it worked for me, i can jump now.
There was one thing i saw during the original, bugged mission. There was only Kappa 2 from the Kappa-wing around, no 1, 3 or 4. At the end, when all ships have jumped exactly this Kappa 2 is still flying around near the first jump node. I think this fighter is keeping me there, because if he doesnt jump out of the system, then the primary mission goal isnt achieved and so i cant jump.
In your mission, all 4 Kappa's are the, escorting the Faustus-vessel to the other node, jumping out with the Faustus et voila, mission goal achieved.
I hope that will help you.
