I haven't gotten to Hrakert yet, but I believe that I have found a new bug.
On Manaan, when I had a female character talk to Viglo (the drunk Sith in the bar), I chose the option to offer him a drink. When he responded, the wrong subtitles were displayed -- I believe that they were supposed to go after he had his second drink. In addition, after his second drink, he didn't say anything, the conversation just cut to my dialog options. Also, is there any way to get anything useful out of Duan and Viglo?
