Okay, playing KOTOR2 on an xbox 360... As far as i know i've got all the patches and i still get the sound bug (though i stop noticing it after 5 hours or so), and occasionally there are some odds pauses in dialog, but nothing too bad. HOWEVER, i just ran into a huge bug on Nar Shadda. In the bottom of the Jekk Jekk whatever, when the Ubese take down the Quarren, GoTo electrocutes the Exile, there should be a cutscene, but i awake next to the ventilation controls with no way out of the underground base. Both doors are magnetically sealed. I can walk around the base, but cant find anything to do. The first time, ran into the corpses of Hannarr and Kreia, and fought a couple injured Ubese, got stuck, gave up, reloaded game. Second time, Hannarr and Kreia lived, but did nothing, and was still trapped in the base. I dont have any saved games from before i entered the ventilation ducts, and i'd rather not have to start over after 14 hours of gameplay. ANyone familar with this prob?
