That is true. I did the same thing, recruit her and not recruit her, still same effect. All she ays is "That was some fight, glad we made it through." or something like that, with both options. (I saved the game and restored back to try the other option.) As far as I can tell, the quest is bugged and cannot be completed. I also tried revealing myself as a jedi at landing to the grouchy bad tempered old man mechanic, and not (keeping my ID secret), also no change to quest outcome. Yes I talked to the militia Lieutenant to talk good about jedi, everybody etc. (Multiple save game options, believe me) I hope that this is one of the bugs fixed by TSL Restoration Project, but for now, they do not have a temp fix yet.
