	// add stub death callback, because in _codecallbacks_common.gnut there is
	// CodeCallback_OnEntityKilled which is only called when an entity is being tracked. An
	// entity is set to be tracked if it has a death callback for it's class, unfortunately this
	// is then relayed to clients and used for client side death callbacks. The end result of
	// not having this function called is that clients become completely unaware of any grunt
	// deaths. A noticeable difference here is that grunts do not play the kill confirmed audio
	// except on War Games, which does register a callback for grunt deaths to make them dissolve.
	//
	// Whilst this may seem like a bit of a hacky solution, it is generally better than simply
	// tracking all entities. If a different callback is created in the future for grunt deaths
	// that is not specific to a gamemode, map, etc. then this could be removed
