In single player Minecraft, I've tried to map my surroundings.
However, my maps are not lining up.

As you can see in the 1st picture, the top 3 maps on the left are aligned well, but the one on the bottom left is misaligned somehow.
These 4 maps are of the 1st zoom level (default).

The two maps on the right are also misaligned, and they are of the 2nd zoom level.

The numbers I have placed beside the maps indicates the order in which I created them.

Is there some way that I can fix this issue, or will I have to start my maps again on a different world?
