Ok. I just find this sortove annoying when doing an LP and getting 4 of the same treasure.
I would think they lead to a different treasure farther away. I got the maps from the same area of underwater ruins. That may also be why. I just hope that they make it to where they show different treasures no matter how far away.
It also seems to dupe items when you just pull stuff out of a chest and do this. I did that once by accident
