Re: Regenerate map under existing factory, any ideas?

I haven't noticed memory leaks.
Running game.player.force.clear_chart() afterwards forces the game to forget all map data so the map view looks nice after the surface update.
Another improvement would be to call game.delete_surface(nf_surface_name) once the script is done to reduce save game bloat from additional surfaces.
Deleting the whole surface at the end you might save some performance by omitting delete_chunk in the loop. Depends on how delete_surface and delete_chunk operate though. From my limited testing it seems faster to leave generated chunks and delete the complete surface as last step.
Here's the script preserving concrete while updating the surface beneath.
I turned it into a tiny mod automatically running the update as migration script for testing.
