Well, what I mean is, I fly from planet to planet, but nothing more seems to be changeable in the game world. I seem to have exhausted all NPC dialog, and entered all areas that are open to me.
I guess the biggest things that jump out at me as being a problem are that I can't find the Jedi on Nar Shadda, Mira and Hanharr never appear, The Crimson somethingorother pirates never come and complain about my using their landing spot in the refugee landing pad, and the Exchange never sends me a message to meet with them in the Jek-Jek Tarr.
