1)

You have to follow Kevin P's Tutorial from

setting up the file structure for map making at the beginning of the tutorial and

2)

Upon a successful loading of the map in game towards the end of the tutorial.

Once you have placed an object anywhere on the map and saved the changes in IL21946>MAPS(a new folder you make)>
Ceylon then copy and paste your changes from the Ceylon folder to MODS>Mapmods>Maps>Ceylon.

These are very basic start up maps there are no objects on them what so ever.

After I have followed Kevin P's tutorial from a succussful loading of the map and following the above I can save a mission on every map no problems.

I hope this clerifies things.
