I had the same problem with a server my scripter scripted for me
if you want to delete 1 of that maps (map0)
you have to go to the top and search for the map activate lines
delete then the one Map 0
and add a start on map 1 ( not start from map 0)
or you change the the maps of the (maplines)
like make map 1 to map 0 (copy the map/object lines) into the section of map 0
then you can make that with map 2 aswell and delete map 3
rename map 0 to map 1 so that you got the same script of map 0 but with a different name and (mainmap)
