Which means that some of the nodes were deleted from the way but the way still exists... The lack of history of a previous version would suggest that either there was no previous version and the way was created with existing nodes, or that potlatch removed the previous way and replaced it with a new way which due to some communication issue then potentially showed as if the nodes were POIs which the user then deleted after the fact and for whatever reason allowed the way to be corrupted... The fix would probably be to undelete the individual nodes that make up the way... d
