Prevent scrolling of map during autosave

I often move the map around during game play.

When doing this during an autosave the map stands still but after the autosave has completed, the map suddenly moves to another position. I guess it moves to the position where it normally had moved to without autosave. Try:

1. Set autosave to 5 minutes or so
2. Start a game
3. Close to first autosave begin to move the map by hold down right mouse button and do this until the autosave has completed

Result: You may find yourself on an unexpected position of the map.

Sometimes the map moves to an unrevealed area of the map and you get presented with a black screen, not knowing where you are :-D
