Either Proxy [OWS] was spectating with his flashlight on, or we have ghosts.
Bug duplicated after I was seeing this light flying by now and then...
What I didn't notice, however, was that spectators can control
other player's flashlights as well.
Oddly, it stays to the right, and there is about a one-second delay in between your movement and the light's movement.
Note that you must turn your light on
before spectating.
While amusing, a light shining over your head makes you a much easier target...
But I'm thinking the mod has specters.
