Make sure connections close properly, without weird error messages Remove player map entity when a player disconnects from a multiplayer game Close server properly when host disconnects, handle ServerClose on remote clients Don't mix JSON decoders and raw TCP writes Actually handle incoming packets from remote clients General code cleanup for simplicity and consistency
