Xbox 360: I played through the mission "The Man who would be Jack" and killed the Body Double. At that point the mission was check-marked as being completed. However, almost immediately afterward, i was killed. When i was revived, the mission was not check-marked. So I fought my way around looking for the Body Double a second time. Couldn't find him anywhere. I then saved and quit and started the mission over. Once again (as expected) there was no checkmark, the mission was incomplete. But despite a thorough search i still could not find the Body Double anywhere. Is this experience known to others? How can one solve this? As things are, it's a game stopper if I can't find him and finish the mission. Insights and Advice appreciated.
