Maps seem to work okay except for in realms. After crafting a map the first time it's good and shows indicator and map is taken from the grid you are currently in. When zooming the map on anvil it generates blank maps with no indicator. It's not until you craft to max zoom that the map works again and indicator appears, however the map generated at max zoom is from the grid from spawn area and not from where you are currently. I have noticed issues with maps in v1.0.2 as well and still in v1.0.3. Thanks
