How to use the campaign editor

[The_wand_mirror]

So, i make a map. add it, get in it by clicking edit in the campaign editor. I edit it. I save it, get the thing that i have an unnused map it my campaign. Click OK and save, don't know what's going on there...

I change the tileset of the map making it w3x, it leaves the other one a w3m file behind in the same map with it and the campaign icon etc. doesn't get changed. I import some files into the campaign and make some units and started triggering something in the w3x map.

I realize the w3m file is still added so i delete it in the map and in the campaign map list. I save the w3x map and close it, i save my campaigna and close it. I open the w3x map and the thing i've done is gone.

How am i supposed to work with this diabolical contraption of confusion.
