here's what's happening: After finishing Kariban, Manaan and Tattoine, I was supposed to come back to Manaan (I'm banned from there because of my "planet's final enemy's dark choise"), but Leviathan got the Ebon Hawk and blah, blah, blah.
Then I escaped the Leviathan, played the "shooting mini-game", got some dialogues and now I can't leave the ship or choose another destination!
Another interesting stuff is that I can choose my party memebers even inside the ship and if I change the party memebers, they suddenly disappear from the ebon hawk.
Mission is an exception: if i choose her to my party, I got 2 Missions: one at my party and another at the Ebon Hawk(????).
it looks like I have landed somewhere, but what do I do???
Thanks,
Orlando
Can't leave Ebon Hawk!!!
I must've seen ten or more variations on this bug, and I still don't have the faintest idea what causes it. If I had to take a stab in the dark, which is sadly all I can really do, then I'd suggest redoing the Leviathan sequence, perhaps choosing a different destination planet when you're departing from Korriban and/or selecting a different character to break jail once you're captured. If you haven't already patched your game you might try doing that, although 1.03 is pretty bug-riddled. Sorry I can't be of more help.
