So I'm playing the game for the second time as a Light character and when entering the Dark Tomb in the cave you meet Malak, and then you start fighting. Ofcourse you lose, the message appears that you aren't killed and normally you move on to the next room but I get the message that my entire party has been killed and have start over again ... duuuuuh ...
I entered the cave with no party members, with one, with two, I killed every living thing in the cave, visited another planet and returned but nothing helped

I didn't encounter any problems playing the Dark side and now I have crashes during the game, dialogues that skip, characters that won't move etc . Can't believe I actually paid money for this :p
