I can confirm there are other chests. I backed up my world, enabled cheats and did a /locate buriedtreasure and found other chests in the area. But I have had about 15 maps, all the same location pointing, to a chest I already looted and destroyed. I just tried to complete uncovering one of the maps and threw the rest into lava to see if that would do anything. If that doesn't I'll throw all treasure maps into lava and see if I get a new map. Seems like the map number never increments or something.
