This seems to be caused by the matinee actor on Highrise and only appears to be reproducible in a packaged build of ShooterGame, not from the editor. See attached UDN for more information.
In a client build of ShooterGame, start playback of a demo and skip to a later time, either using the on-screen controls or with demo.GoToTimeInSeconds. After two skips, the game will crash with the following error:
Fatal error: [Link Removed] [Line: 212]

There's no existing public thread on this issue, so head over to AnswerHub just mention UE-114049 in the post.
