Actually it's been pointed out to me that "if (updatelevel)" or "function onUpdateLevel()" actually works and does exactly what I need.
Thanks for the help though! Glad to know there is actually a feature for this.
So just for anyone that might be searching for a way to do this months from now.
if (updatelevel) checks to see if the level has been updated (not if an npc has been initialized or created) So that you can have database npcs know if a level was updated or changed.
