To the best of my knowledge you cannot create maps with multiple terrain (season) settings. By this I mean winter & summer move rates mixed on a map, it will use what you saved the map as so if summer any winter as in snow is cosmetic only.
I am playing a Campaign Russia vs USA currently 11/69 & the generated map can do this.
Roads fields (crop stubble) & snow covered hexes all cost 1 extra MP. Non snow covered open ground however uses summer movement rates.
Is it possible to create a user map in this fashion?
