I had this problem before. Os there a way to alter the save file from the start to fix it so that no matter what you do you're set to get mira? Also is there a way to say slip a file in the override to do this for all your games as well?
Just make sure that you're an LS player before Nar Shaddaa :)

This gives you the chance to tell the walking carpet to "get lost", or something of that nature, and you get to have Mira no matter what. ;)
