If you plan on downloading and using this, my experience with it has been:
Worked fine up until Bao-Dur on Telos. The initial problem was that Bao-Dur was not showing up to drag you out of the crashed shuttle, the game would be black screen but still functional. By making a new save and loading, I managed to get rid of the black screen problem, but Atton and Kreia would stand there and they weren't in my party, when I added then, I had duplicates on the field, two following, two standing by the crash.
So I tested file by file in the override folder and found out that the classes.2da was causing the problem. Without the classes.2da, Bao-Dur dragged my party out of the shuttle. But another problem appeared when I tried to level Bao-Dur up. All his skills are considered cross-class byt the game and he hasn't gained a feat yet. I said yet, because I got tired of trying to fix Bao-Dur and decided to keep on playing for a bit to see if the next character who shows up will be bugged too.
