I have a grave in the Nether that I seem unable to retrieve. It is at coordinates x:-9544 y:95 z:-4219 in the Project Ozone 3 server. ign: Greeniac916
UPDATE: I died once again in the Nether and am also unable to retrieve the new grave.
UPDATE 2: I died in the Hunting Dimension and am unable to retrieve the grave there as well. I was able to collect a grave from the Overworld though.
