Okay, I think I can reproduce this problem on Windows as well.

1) Copy the default map-gen-settings.example.json file to map-gen-settings.ribbon.json
2) Edit map-gen-settings.ribbon.json and change "height": 0, to "height": 32,
3) Create the map using the factorio binary --create flag: (Full output ...
