1. If it looks like the map you received from the book was incorrect its because the image you see on double click no longer matches the coordinates of the map, but the coordinates are still the same as when you placed the map in the book.
2. If the number of contained maps displayed on the book(item) is too low a simple drag drop will fix it, this is a common problem and it in no way influences your maps.
3. Some of you may have questions regarding the book functions
-the small gump only shows maps that are on the same map as you and only the closest 10
-the tracking button only works if your skill in tracking is higher or equal to the number of tiles between you and the treasure
1 and 2 will get fixed with the next restart and all your maps should return to normal.
