I was doing the X-8 Data Retrieval Quest, and one of the computers that you download the student record off of has disappeared. Since the only two doors leading out require a key to open, there is no way to leave. I have no saves from before entering the test area, so reloading a save is not an option.

Are you sure you are missing a computer? I have noticed in different runs they switch spots. Make sure it is not in another spot.

If it is missing, your only option is to load an earlier save. =/
