Copying or exporting maps?

I have been trying to find a way to copy/paste maps without them breaking the engine, primarily when loading into a copied map. I want to do this because I am trying to purposefully disorient the player by changing the environment, weather, camera, (etc), in a way that would be impossible or very difficult with events. (maybe js scripts)

The way I have been trying to do this is by creating a new map in the editor, then going into the project folder and copy/pasting all files from my target map. Then going back into the treeMaps.json and infos.json files and editing them to recognize the new map. My problem is when I try to load into the map I get an error saying it was a linking issue and tries to reload only to fail again.
Is this way of exporting maps nonviable, is there a better way to do this, or is there just simply something I am missing?

Thanks! - Cherry

Hi, normally if you right click on map, you can copy it, then paste it, even in another project if you close the project and open another.
