I have tried setting 300NAR_Exchange_Gap to 10 and 8, as well as increasing 300NAR_Exchange_Favour, but neither seems to work. Im using the Global Comparison tool with my save game and a friends save game where he has completed Nar Shaadaa, and there are a few more things yet to try. *sigh* its slow work, but at least my ship is back to normal.
I do not believe it has to do with killing the Exchange leader in the Refugee sector. But in saying that, Chris previously has said that you dont have to complete the red eclipse quest to get the exchange meeting, so maybe more than one thing gets broken when this quest breaks.
Theres just something im missing, but i'll find it i guess. I have made Chris Avellone aware of these problems and asked him for help with the variables, so i'll see what i get back from him.
