Go to editor and there are always 3 RNO files in your cossacks directory.

One of them is the map you have just generated in single player. They are automatically stored there.

So if you generate 3 maps in a row, those 3 RNO maps will be the last 3 maps you generated, just look at the date & hour of the map to determine which one is the one you last created in single player.

Do not change the start positions in the editor, do not change nations from one place of the map to another.

RNO maps are limited, its far better to create new maps, but then you won't have peace time, unless you script it.

Hi again. The map is finished, and fully operative but it has got a problem. I put 60 mins peace time in RNO options, but when i start to play AI attacks me at 15 mins or so. I dont understand why. Could anybody help me?

If anybody want to download map i paste a link to do it:

I'll have a look tomorrow, unless someone else knows what might be causing this?

Tell me, which color are you playing under? ( red, blue or purple). I played with red.

Also, if as you said in one of your previous posts you want to play this map with 2 friends with 60 peace time, why don't you just agree not to attack before 60 minutes?
Or do you really want the peace time to be there?
If so and if I can't find out what's wrong with your map, I'll give you one with 60 peace time and any requirements you want.
