The latest version should center on the middle of the stored map. There was a race condition in the older versions pre 9/30 that made it either the iOS device location or the center of the map.
The saved missions have a very limited zoom so as to not take up too much data storage. There is still a bit of weirdness with displaying the local files. We are working to clean it up.
Showing the local position and the saved mission location could potentially span the entire planet so we probably won't offer that.
