Ok I reworked it: http://www.file-upload.net/download-277 ... d.ula.html
Always keep a distance to the edges of your map. If you press g three times, you can see a big white grid all over the map. It will not be shown ingame, don't worry. Bottom line, to prevent units from falling off the map, Paraworld doesn't use the entire map. It 'cuts off' a part of every map, which is sized four of those squares. So if you have set your map's size to e.g. 1024x1024 you can only use the part inside that box, which brings down your functional map size to a smaller value. Don't place any objects important for the game into that dead district that starts at the map's edge (in mapeditor) and ends four squares away from the edge, from each side, as those objects will not be usable. Because of that, you couldn't play the map.
So what I did now is I took a template of your map and inserted it into a huge sea, so those edges will definitely not destroy your functional desert map part. I admit it looks a big ugly now, but it will work.
