Usually in slaughter maps, there's a small chance a Lost Soul will be completely unkillable. No shots will harm it, splash damage wont harm it, autoaim doesn't target it, even the command 'killmonsters' wont affect it. However, it is still solid, and it can still hurt and kill you, so you basically have a lost soul after you until the map ends. Not sure what exactly seems to cause this.
