I've searched through the forums and libraries and can't seem to find out one simple thing: how do i save any changes to the world?

I only noticed it today ^_^;; I have a scene where an NPC walks out a house and goes stands a small way off. I saved (testing my saving system) and relogged. It loaded up and the NPC was back in its starting point.

I figured I should just save the entire map when the player saves. But..how?

Any help? Please & thank you's ^_^;;
