I know you said the mod is supposed to be used while starting a new save, but I feel like it'd be really useful if there were commands that would force a concreep check, full or gradual with the specified tile prototype.
/concreep_gradual <optional-tile-prototype-name>
/concreep_full <optional-tile-prototype-name>
For example in Krastorio 2
/concreep_gradual kr-white-reinforced-plate
/concreep_full kr-white-reinforced-plate
