When playing the Obi-Wan vs Anakin mission (on mustafar),
This issue occurs when playing as Obi-Wan
when you get near the end, right after the cut scene where obiwan and anakin are fighting, then the bridge breaks apart, and the cutsene ends and then you are able to fight again. At this point the issue occurs where Anakin will actually fall off of the platform at the bottom and into the lava. He does not die, he just stands in the lava, screaming, and the only thing you can do at this point is manually abort the game. This happens every time I play on this level as Obi-Wan.
I have also seen others post about this issue on moddb.
Thank you for your help!
PS. Great Mod, cannot wait until version 2 comes out!
