Very nice mod, but it seems incompatible with RSO - the resources that were once autogenerated by RSO outside the starting area are gone after using this mod - neither uncovering the area again nor calling RSO's regenerate function will make the resources appear again.
Looking closer, not all resources arte gone, but almost all. I mapped resources around my base befroe deleting chunks, and while almost resources deleted by this mod in a radius of 2000 around my case did not come back, a single one did come back. Using bob's mods btw.
Furthermore, when uncovering a large area with console commands (player.chart) the save game size incraeses and the time to save increases, but wqhen using delete chuinks, the map visibly shrinks again (most everything becoming black again), but saving takes the same time and the savegame size is still blown up, so I suspect the mod merely hides, but does not actually delete the chunks.
This mod does actually delete the chunks and save size does decrease accordingly. I'm not sure what is happening with yours. May be some other mod that has an odd interaction.
I verified that everything does still work correctly. It is expected behavior that 'starting area' resources if deleted do not come back as described in the release notes and on the forum. Tested again with the current version of RSO.
