I'll give that a shot next chance I get, it has to be the hyperspace graphics 'cause we tried skipping as fast as we could through but it always crashes when the (Even in the background) Hyperspace gets half way. Oddly though, It still worked fine if we didn't leave the ambassador on the Empire ship. (We also tried lower all graphics to lowest to no avail.)

Yep, even in Storymode The Esseless crashes in the last conversation with Hakon. Crashed 3 times in a row for me and my mate, we can't ever finish this mission now. We chose to leave The Ambassador behind, my guess is that is the problem since I remember it working for my other character when we didn't leave her behind. That is the error code if that helps!
