Ok so I am pretty much at the end of Nar Shadaa:

 

Spoilers

I have killed the Jedi... T3 went through the quest to get the blank transponder card and code, I got my hero from Gotos yach, etc... But now when I go to the mechanics guy it says I still need a blank transponder card? Whats up with that? I cant go on in the game!!

eh...you shouldn't need that after that...you've got the card that's keyed to one of someone else's ship so you could go..um, do something that needs to be done... meaning, the ebon hawk's original is gone...just don't go bug him anymore about it and go your merry way.....

 

 

the do something that needs to be done is cause this ain't the spoilers section and I don't want to give away any more then needed
