i cannot access the map generator screen when using the freeplay or sandbox in the custom scenario

If you made custom scenario map in the game editor then the map generation settngs that you chose when you started working with editor will be used.
Copying freeplay.lua or sandbox.lua only affects ingame rules like is god mode enabled, which technologies are available, preprogramed ingame events (used in campaign scenarios), etc.
These files doesn't affect whether map generation rules. Those are stored in the map itself.
As far as I know map generation screen only shows where there is no pregenerated map available for certain scenario.

thanks for the help works fine
