While editing north-western Poland yesterday (April 10) afternoon, 
something strange happened. It might be related to the DB 
rollback.  I'm not sure when I started my editing.  After having 
finished a few hours of editing in JOSM and uploading my last 
changes, I also saved the JOSM data layer to file (15:42 GMT).

Then when I started to generate tiles (I run tiles at home in xy 
mode, based on coordinates in the .osm file saved from JOSM), I 
discovered that parts of my roads were missing. This area is just 
east of the city Stettin/Szczecin in Poland, 

When I opened this area in JOSM (new download, not my old data), 
it looks like a mess. Not only were some of my roads missing.  
But parts of footpaths and a cemetary from England had been added!

I didn't change anything in this mess.  I believe it is still 
there, and in this morning's planet.osm.
