Not sure what the exact issue is in terms of the components, but noticed on two separate occasions that as soon as someone hit the play button on the jukebox in the Madcat map, the audio would immediately start looping, and the game would begin lagging, and within less than a minute almost everyone will be getting loading screens every 3 seconds until they crash. This problem doesn't exist on the live version of the game so I don't think it's the map.
