Unfortunately if it's a bug with the xbox version, the only solution is to load a savegame from prior entering that area, preferably before the whole sequence of events involving Mira.
Always keep more than one savegame and save before entering a new area.
Moving this to the xbox tech forum...and welcome to the forums
