[minor error]

On the ship maps, there are very small rooms that contain two large rotating fans - with a golden light behind shining into the room, the light beams themselves are projecting incorrectly to the left or right of the fan - instead of projecting into the room.  I've only seen this with the golden lit ones for some strange reason, this glitch happens in 99% of the very small rooms these fans are in.

I grant you this is a minor glitch - but the effect of those fans are quite good!  :)
