Map Lighting

[Locotomo]

When I change the lighting of a map from „none“ to anything else (moonlight, dusk..) I can´t change it back to „none“

I had the same problem. Ended up closing the map and starting over. Tried everything else before that.

If you have turned ambient lighting on then presumably you want ambient lighting of some kind. If you don't want it then switch it back off. I agree that you can no longer select none, but switching it off is the same thing as having no ambient lighting.
