Can yoiu make mira a jedi?
Because I can't. I can get her to agree to it, get a success with the influence thing, but then it never goes anywhere. Is it a glitch, or is it only doable with a mod or just on the xbox version or what?
You need to return to Nar Shadarr. Take Mira with you and make your way to the entertainment area. Just before you get to the door, you will encounter a cut scene in which you can turn Mira into a Jedi.
All that you love will be carried away
Before you do that, you have to talk to her on the Ebon Hawk; get on her side, talk about different stuff, etc. Eventually, bring around the subject of the Force/life/Nar Shaddaa, and if you've influenced her enough, she'll be receptive; if she's not, keep at her with the dialogue; I find being polite (& occasionally apologetic) always helps.
