Hello,

I think we are in agreement: I merely fixed the outer outline of those buildings because they should be traced on PICC imagery (based on "cadastre") and not on aerial photographies, which always give a distorted view of the reality.

I correctly respected your desire to split the building, and since the new situation is that those are 2 buildings (whereas current PICC imagery only shows them as one), I added the following note "According to changeset 146615324, this building is now split into two units: 132 and 132B" on both objects.  This will alert any other mapper coming around and deter them from wanting to merge them again.

As you may know, the map you see on osm.org is not real-time but pre-computed PNG images that are generated every few hours or every couple of days.  Each zoom level is refreshed more or less frequently, that explains why some zoom levels still show the old situation.  Have no worries, that should fix itself quickly.  Also, as you have probably looked at the map in this street *before* performing the changes, chances are high that your browser still stores the old PNG tiles in its local cache instead of downloading fresh ones.  Closing the browser or forcing a cache refresh (F5 or Shift-F5 or CTRL-F5) sometimes helps.  ;-)
