Reading the description of the mod, it is mentioned that you can add those 2 maps to the Atlas, but I have tried several times, without success.

The behavior I was expecting: to be able to view the contents of those maps like any other map in the Atlas; that is, literally add those maps to the Atlas and be able to view them from within.

The -only- behavior I have seen: to be able to add an empty magic map or an empty maze map, so that they count as normal empty maps and serve to expand the Atlas.

Is there something I'm doing wrong? If the last behavior I describe IS the actual behavior, then the description should be improved because it leads to confusion.

You just make a map and add it to the atlas as normal. Work just the same as a normal map, with same restrictions

In that case @MehVahdJukaar, I don't know what I'm doing wrong.

The screenshot shows an Atlas for each map resolution (1:1 to 1:16), all of them with the same starting Overworld map.

I use the cartographer/crafting table to expand the Atlas, but neither the magic or maze maps produce any new instance.

I'll test maybe something broke. Also the magic ones are always 1:16

Yes, I remembered that maybe the maps had another scale, so I tried them all but to no avail.
