	SCRIPTERS READ THIS

	The purpose of this function is to fixup npc fields coming from all the many places they can come from, so that code doesn't break them during DispatchSpawn.
	If you want to fix an AI field on spawned, you should do it in ai_spawn_content, unless the field change is related to code functionality and needs
	to change before code spawns the AI. Then, it should be here.

	Thanks
	-Mackey
