4-Add many trees-objects-splats-splines
5-Add territories
6-Move some territories from one place to another
7-Change both atmosphere settings.The one with blizzard and the one with no blizzard

Change the custom atmosphere,so if cold tech disabled in game, atmosphere to be different from the default custom atmosphere.What that means?
When winter atmosphere used in a map,need to select relics presets (that is only very few for winter),otherwise there is no cold or blizzards.(Still atmosphere mode is lock so winter cold and blizzards can not be custom.)
But custom atmosphere can be created and used only that there is no cold or blizzards.
So now maps that use blizzards can also have a totally different custom atmosphere and can be used when "cold tech" set to disable.So for best result in atmosphere disable cold tech Enjoy and Rate up.

Add action markers.

Correct the map entrance point.

Make bigger area in bases.
