Anyone have an issue where on neoforge 1.21.1, any new maps added get used up and basically never create a new area? I put in a stack of maps, and it only drew 2 and then said I had 0 left. It made map scribbling sounds 10 times overlapping so maybe theres an issue there? It happens in survival and creative. I have only Map Atlas and Moonlight lib.

Adding as well I tried all the versions and they do the same thing.

Having the same problem, work around for now is to keep the empty maps on my inventory instead of in the atlas.

Steps to not lose maps:

1. take the atlas put in player crafting with only 1 single empty map
2. atlas now has 1 empty map
3. move atlas to hotbar so that it updates and adds that 1 empty map to it
4. then go back to the crafting menu to add ONE more empty map
5. now move it to hotbar again so the atlas can add that 1 map

eventually the atlas will have nothing in range to add so that 1 single empty maps stays as "empty map: 1" in the atlas. at that point stop adding empty maps and keep the rest in your inventory and only add 1 empty map when the atlas consumes that 1 single empty map. Never store more than a single empty map in the atlas

Can confirm that every time a map is written, the Empty Maps count is set to 0 instead of being lowered by one
