Special_Lifeform: Replayed the game last year, the only serious bug I encountered was the loadscreen crash on Onderon. Turning off the shadows in the graphics menu solved the problem for me. In my notes text file for the game I found the following, maybe it can help you solve the problem:

Edit: Had a swooprace bug once, this could be solved by turning on Win XP SP3 compability - iirc those fixes were only required in the specific situations/locations and could be changed again everywhere else. No idea if anything of this helps you since I never encountered your situation, but it might be worth a try.

"Hello everybody!

I just created an account specialy for this topic, because I know it's the kind of bug that make people very quickly crazy, including me.
So if I resume all the solutions I found until today on the Internet, we have:

:down: Change your graphics options (resolution, soft shadows, AA, texture quality, anisotropy, etc)

But these solutions don't work everytime. After that, I read many people giving the next solution:

:down: / :down: Equip your party member with a lightsaber

That's a good way, and it works very well... But there is some distracted guys in this world who forget to build their lightsaber before going on Onderon...
And for theses guys, here's my solution:

:thumbsup: Equip your party member with the plasma torch!

I hope it will work fine for you too"
