Hi Simon,

I am not sure what you mean here, can you explain what you mean by ‘I doubt that something has gone wrong’?

To my understanding the redaction should have brought the nodes and ways back to the state from before the copyright infringement. For the sample of buildings I checked that state was being a rectangular way tagged as building=yes and thus also 4 nodes. Now the way has three nodes, and thus is a triangle. To me and probably most others this looks like a unsuccessful redaction.

Cheers,

I doubt that something has gone wrong.  A redaction is not a revert (aka
it doesn't restore a previous state of an object), so the result depends
on what happened in the changeset that is being redacted.

If a building was added then it will simply vanish, if the geometry was
manipulated (for example by removing and adding a node) the results
might not be what is "expected".
