This would probably be better in the Tech Support section, but I can't figure out how to get Steam to tell me my game key.
Probably best to stop reading if you haven't finished the Corporation Troubles plot line.
The mission asks me to talk to <invalid> at Saturn Research Station (which is where the corporation owner was for me). Since the corporation was sold by the owner, this is the second rep gaining mission I've been called for (I'm assuming both shouldn't have happened), but the first worked fine. I also have an unlabelled corporation rank of 1 in my pilot status, where the main plot one was.
So I can't complete this random bugged mission, because the person I'm supposed to talk to has disappeared to spend their cash on some Space Fuel or something. I can't abort it either. And I'm not sure if my Corp HQ is supposed to do anything except look pretty, because it's not doing anything... except looking pretty.
P.S. Steam version of X3AP, Terran Commander start.
