I think the new nether update broke the maps. Whenever I go off the boundaries of the maps (No matter what level of map), it places my player indicator, where it shows you where you are exactly of the map, somewhere else. Usually in the middle or somewhere else entirely different. It's confusing and it makes the maps harder to use.
Thank you for your report!
