(some light spoilers possibly...)
I've done every single quest that I possibly can do on this planet, I have annoyed the exchange as much as I can but have still not received an invite.
Anyway, my problem is regards the 'Landing rights' sub quest, which I assume is necessary for continuing the storyline (since i've hit a dead end). I got the quest in my journal, ran back to the ebon hawk - the flying thing quallo or whatever he's called tells me to come over to him, so I do...only problem is he doesn't talk to me. I've tried exiting the area, switching characters, completing every dialogue option possible on the planet that I can find, even leaving the planet and re-entering, but he still just sits there and doesn't talk to me.
I have a similar problem with all the bounty hunters - none of them respond: Mira, the wookie, the sisters and the other one - all refuse to talk to me.
I've run out of ideas here, I assume you need mira's help to take down the exchange and hence complete the world, and I assume that the dialogue tree with her is triggered after I've done the 'Landing rights' quest, I've done some reading around, and no-one else seems to have this problem, and it seems too obscure for a patch to fix.
Does anyone else have this problem? or any suggestions as to fix it? As it stands I can't complete the world and therefore can't complete the game (reverting to a save is not possible btw, i thought it would fix itself later so i saved after the problem started).
Any help on this would be greatly appreciated, so I can go back to enjoying, not hating this game
