This has happened twice in a row in the past 20 minutes, but never before. I join a server, was running for about 5 minutes, then it would "rewind" me to a point 5 minutes or so prior, and when doing so I can hear sounds, but cannot move.
When this happens, I cannot access the UI either (TAB or ESC keys do nothing, had to Alt+F4 the first time, currently minimized). Game is NOT frozen when this occurs, I can still hear sounds, minimize/maximize the game, etc.

Before this happened (both times) I kept hearing random in game sounds (Cans opening, bullet combining sound effect, etc.) that were occurring extremely commonly. {F29252}
