Dead Parvati

[JonathanVQP]

I have been totally enjoying this game but I came across a strange bug that I don't know if it is either a game bug or something that I don't know how to fix. Attached is a picture of one of my companions. During  one of the missions where I had to get a science weapon, Parvati fell and "died". When I add her as a companion in the game, she talks to other characters but her picture is blank  but her dead body is with me wherever I go with her as a companion. She can't shoot but lies there. I don't know how to resurrect her.  Can she be resurrected as a character or is she "dead weight" now? I progressed too far in the game to go back before she died.
