When I create a new map, the content will start in the center of the new map. As I wanted to create a big mapwall I thought that - as it was in the past - the map start at the last point of the old map I used. It is not possible anymore to crate a mapwall if the map starts at the center instead of the last position of the last map.
Oh the picture you can see the map on the left side I used for navigation and the position of the rail station. The new map on the right side was created after crossing the right border of the left map. The new map has the same zoom size (Level 4/4).
I have checked the behaviour in many places and it is the same everywhere.
