 That is what causes those error messages to be printed (ie, the object it added
in to the buttonlist when the map was loaded does not match the object now
there, or the object now there is a defunct object)

      a different map, I dunno the CF internals).

 Are you running CVS or 0.98.0?

 There was a bug in 0.98.0 that resulted in something similar to what youu
desribe - when maps with in memory were reset, the freeing of the data resulted
in the above situation.  That is fixed in CVS.

 the update_item is a sort of harmless error message.

 Sort of harmless in the sense the client will just ignore it.  Not completely
harmless in that it does take up some bandwidth to send data we will discard.

 The fix for the bug (levers/other object player is standing on not getting the
face updated) is not completely satisfactory.  It does work, with the cost that
we send some false updates to the clients.
