It was awhile since I've done that mission but I can't remember if there was an event that occurs at that spot. I think there is a save prompt at that point. Turn it off and proceed with caution (if there is a save prompt, turn it back on when the game is done saving). I do remember that a side mission will appear later around that area in the form of an ECHO.
