KLS is there an issue with e.g. 
	Code:
	if (defined($entity_list->GetMobByNpcTypeID(115132))) { 
$entity_list->GetMobByNpcTypeID(115132)->Say("Aye, we wouldn't want ye fallin into the pit now would we."); 
}
 If the NPC Type ID is unique for the second one?
This also lets you know if the other npC is dead or not if it doesn't return defined...
