Is this a known bug or did I do something wrong?

I created a mission last night and I didn't see a save or exit button, so I just left the tool. This morning when I logged back in, I saw "My Mission", clicked "edit" and it had saved the name and description, but all of my map items (ships, asteroids, etc.) were gone. It was a blank map.

Also, I thought an older version that I used allowed you to use the ruler to see various firing arcs. I can't figure out how to show that information now.

Overall, a totally awesome tool.

if you hit 'ypdate preview' or go to the preview your mission will save, but good point; that's not really intuitive.
