So once the game was over and the credits started rolling, the following images display the text that scrolled, in place of the usual credits. This was undoubtedly caused by a mod somewhere. I mean, I don't care; it's after the game finishes and has nothing to do with game play. I just thought is was amusing.

Has anyone else ever seen anything like this? It gave me quite a chuckle.

It is a code! Unlock the message for KOTOR III!

your dialog.tlk may be corrupt. have you noticed any other dialogue or text where it shouldn't be?

No, I have not noticed any other dialogue glitches. I do have a mod that adds extra dialogue, though. But like I said, it's only the credits, so I don't really care. I just thought it was cool so I shared it with you guys.

EDIT: Actually, now that I think about it, a line of dialogue from Carth's dialogue tree only spoken if the main character is a woman popped in there, and my character was a man. The line where he says something like, "All right, all right! You're the most damn persistent woman I've ever met!" showed up. I was like, "Huh?"
