I noticed that this bug has been a major issue for many, including myself, and many, like me, have sent many tickets addressing the issue only to get generic or unhelpful solutions. I here to tell you that there is a solution, I have tested it my self and have had friends who also play Sith Inquisitors test it and have had positive results. The solution is simple yet complex for some. The reason these issues occur is that there is a binary error with the data that is being processed in the game. In simple words, its not the game that glitched or bug but your computer has an issue of processing the data in the game. For example, when doing the conversation part of "Andronikos Revel", your pc is trying to process to much data at one time, so it is unable to finish this process and leaves many people stuck in the conversation and unable to do anything except press the ESC button to reset the conversation. So here is the part that you are wanting to know, "how do I fix this Bug". the solutions, even though maybe hard for some people to do. 1.) Buy a newer computer with a better Data processor 2.) Try using a different computer to complete the quest.( this is what my friends and I did and is worked. Also you may want to reset the quest and start it from scratch when you do.) 3.) If the above solutions fail, it maybe a problem with your internet or internet provider. also if you are using a wireless connect, your device on your computer or router that sends/receives the data maybe broken. Well hope this helps. It did for me and a good bit of my friends, Also I forgot to mention this also solves some of the glitches in the Bounty Hunter Class story line.
