Re set the start marker. I saw a map like this where there was a start marker under the terrain at this spot.
Save, and then reload that map.
Give that a try.
Now what happens if you make a new flat terrain map, and place 1 building and 1 start marker and then save while your in the middle of the map? When you call up that map does it stay at the position you left it?
