Apparently it is possible for the game to freeze up due to plot errors. I am bout 12 hours in on Dantooine and because Vrook decided not to get out of his cage my game cannot progress. I am not certain what is more nerve-wracking, software bugs or the simple fact that the game designers released a game that can freeze due to plot issues. Any help would be appreciated. Also this is an issue for the Xbox release as well.
