Describe problem (what you were doing; what happened; what should have happened):
Tombstones have become inaccessible and indestructible. Only myself and my wife are on the server and neither of us can access the tombstone. I have tried running the delete command on the server, and while it said it deleted tombstones, there are two that remained and refuse to disappear. I also can't use the fill command to replace it with air, the command returns:
[13.04 03:34:54] [Multicraft] dracono100 ran command: setblock -548 115 780 air
[13.04 03:34:54] [Server] [Server thread/INFO] [minecraft/MinecraftServer]: Could not set the block
