This should fix a rare crash that happens when the playlists file is reloaded during disconnect. The client fetches the playlists from the server on connect. On disconnect, we want to reload the one from the client so that if the player want's to create his own game, that he would have his own playlists. The fix is to delay the reload of the playlists file to the beginning of the next frame.
