I located the buried treasure from the map, looted the chest, destroyed the chest.  Still get map to same location, and /locate buriedtreasure executed on a backup copy still shows chest there, yet there is no chest from bedrock to high in the sky.

Additionally, every treasure map, no matter how far away it was obtained, returns the same map location.  It's like it is stuck on the one treasure map thinking I still haven't found it.  I have over a dozen maps exactly the same.  There is other buried treasure I can find nearby but never get a map for those.
