I'm looking for a problem at map=15/47.0720/22.1241 and specifically I'm looking for any deletions related to way/84965365. JOSM and the OSM website show only 2 versions in the history, while Potlatch shows several other edits, from January 2016. Why does this difference appear and how can I see what those "hidden" changes do?

Potlatch looks to be showing you node edits which wouldn't have affected the way (so not adding/removing nodes or changing way tags).

This is just one example - find others by looking at the XML for the way and looking for node versions greater than 1.

Thanks Ed. I'm pretty sure one of the many edits of that user deleted a multipolygon relation that rendered the now white area as agricultural (CLC data dissapeared). Is there any way to find out which change did that except going through them one by one?

I checked for deleted ways using Potlatch 1 and found this one: http://www.openstreetmap.org/way/87489584 which was farmland (history times out, but api call for v8 shows tags http://www.openstreetmap.org/api/0.6/way/87489584/8 )

You can get a rough idea where to start by looking at Potlatch 2's history (which shows node changes). Unfortunately you'll have to match up the dates and times yourself - the most recent change seems to be https://www.openstreetmap.org/changeset/36879542 . Their changes don't seem to include relation changes though, so it may not have been them.

The CLC polygons are huge though - it might have been another user some distance from that way.

Another option for way history:

Thanks @EdLoach and @SomeoneElse for your help and all the useful pointers and tools you provided. I've reverted the changelist as the data added was significantly less than what we lost.

There should not be any hidden version.

Indeed, in Potlatch it shows more nodes, wierd
