[mkgmap-dev] data missing in extracts

Hi, Recently I have a lot of issues updating my OSM data. Normally my workflow is updating a region (Benelux) with osmupdate. Recently I have found out the updates are corrupt, all mp relations are not in the map anymore. Today I tried to download a Europe extract from Geofabrik, I cut out the Benelux area with osmconvert and again: no relations in the map at all. Anyone having the same issue? I have no idea how to solve this, I have the latest versions of wget, osmupdate and osmconvert. Don't think it is a step in my splitter/mkgmap chain because the source (o5m) is smaller than the previous versions which contains all relations. Sometimes it works, but often not and today I found out that even the Europe extract was corrupt.
