Nope. The mission is likely attempting to spawn something which no longer exists. It's probably something to do with the RNC Donau, but most certainly not limited to. I actually went about fixing this some time ago for my own purposes, but after taking that artefact, my new, shiny exile status wasn't that great after all, what with Battleship Unity dock-raping me and Juni as we tried to flee! I also had quite the hard time trying to take out the shields of Nomad Battleships with my Barracuda! In a nutshell, the entire storyline needs revamping from top-to-bottom if ever it's to work in a balanced, bug-free manner, and that simply isn't going to happen.
