Some of the bugs I have experienced:
* On Korriban I got stuck in the last room of the cave (the one with the tomb). I entered the room, got the goodies from the tomb, but the exit door didn't unlock. I had to replay from before entering the solo part of the cave. Second time around I got a message from kreia upon entering tomb and the exit door unlocked.
* Towards the end of the game I saw a cut scene upon entering the ebon hawk where bao-durs remote was destroyed by g0-t0. But after the cut scene the remote was still floating round the ship and neither bao-dur nor g0-t0 had anything to say about it.
* Swoop racing is completly broken for me - whatever time I get, I am told I crashed out.
* I could not complete the fuel for telos plotline, I went to see votta towards the end of Nar-shaddar - I had already complete most of the exchange stuff, so maybe this broke the scripting (though it shouldn't).
*Dantooine was unplayable until I edited the ini file to correct the fps bug, incredibly unprofessional. I would have given up here were it not for the forums.
There were many others but I wasn't keeping notes and will not be playing again until a patch is out.
