The current version kind of works. I created several for the last 2 scenarios that worked well. I have been able to create simple missions, but occasionally it will crash. However, I have also had program crashes in the main arena. As to the original question how to download staged missions, try creating a custom arena, click on staged missions in the tower, than select missions. A list of missions will show up at the top for that terrain or you can select show missions for all terrains. Highlight a mission, than click download. I have posted detailed instructions in my previous posts. To use them offline you have to load that terrain at the startup screen. Good luck.
