I expect there is some way for rolling back changes, it's just not exposed to the public interface. That would make it even more easy for malicious individuals to destroy other peoples work, at least if there is no corresponding "roll forward".

Well, if *everything* is misaligned from the satellite photo then the satellite photo is probably misaligned. Try to get good GPS data of some locations that are clearly visible on the photo and use them to correct the image position.

Hmm, geht auch nicht mit JOSM 1090, auch nicht nach Laden des Bereichs in einen neuen Layer. Ich versuche z.B. den Punkt 313543460 zu löschen, der steht alleine, hat keine Tags ...

Hmm, das Problem liegt seit mindestens knapp einer Woche vor. Und ich kriege nicht mal einen einzelnen, alleinstehenden Punkt gelöscht ...

Well, I am using JOSM. My problem is not getting the change rendered or to actually delete it, but to upload that change to the server. When I try, transfer takes a loooong time then aborts with a message about "Bad request".
