In civilization 5 the minimap displays a rectangle, even though civ is actually played on a cylinder - it just means that the east and west edges of the minimap are touching. Sometimes the minimap displays the "calendar line" in a very uncomfortable position - for example I would like my empire to be in the middle, but it appears very close to the edge of that minimap.
I know that after exiting and then loading a game the minimap changed so that my empire was in a different (better) position, far from the sides. Is there any way to somehow control it in-game?
