Re: Unfair disadvantage! I cannot defeat the 9th (Ninth) Sister on Kashyyyk!
Thank you for your help! I removed the disk and after reinserting it and thus restarting the game, I was able to defeat her. It was far easier than previous iterations of the fight, and I am wondering if the glitch was the gameplay mode, i.e. this previous fights I had engaged in weren't playing in the Story Mode but another, far harder mode. The Sister spoke a whole lot less during this fight, and the damage I was able to inflict on her made the fight go quickly. The whole fight lasted maybe two minutes, whereas before the fights were lasting, when I was able to get to the third and final stage of the fight, in excess of three minutes.
I finally beat her and am able to move on!
