As I've mentioned elsewhere, I'm a recently returned player. Just got my fresh new JK to the dramatic duel with Praven on Tatooine (love that location, by the way!) and it was there that I ran across the first big glitch I've seen so far.
Every time he moved around the stage during our conversation, for some reason, the front and back of Praven's loincloth were acting like they were attached to the points he was moving toward or away from. So if he walked toward me, the front cloth would start stretched out horizontally toward me and slowly get reeled in, while the back cloth would gradually stretch out behind him. It was all rather distracting.
I don't remember seeing this happen when I ran this quest before on the same machine. Perhaps it's a glitch that got introduced with the new engine?
