I have encountered an intermittant scrolling bug. I will be exploring the map with my Sovereign and scrolling around the map by clicking and dragging it around. Randomly, the game will stop scrolling and instead just "shake the map", for lack of a better description. The map will no longer scroll in any direction. When I attempt to move around, the map moves a few pixels in the desired direction and then snaps back to the original position. I can fix it in game by simply ending the turn. I haven't figured out how to reproduce this.
