Oh, I DO have permadeath disabled, but how would I get her back?
Viewing post in Quest Involving Cali
Permadeath deletes the character, so any save after her death cannot recover the Cali you had. Your options for getting her are loading a previous save or autosave, starting a new progress, or editing the save file to reset her sidequest back to zero.
Edit: misread comment as saying "I DO have permadeath", see Leo's comment for a better answer
