Well, on my first day as an editor, I made some mistakes.

It’s right there on the wiki, very clearly: Imagery can be wrong. But I didn’t though of that when trying to fix this lot of roads which seemed oddly aligned with Bing imagery. I’m sorry.

I think there should be more advice about that on at least ID’s walkthrough (a link like the above one maybe). I had no idea that the map could be disaligned with the aerial image.

There’s some way to revert a changeset?
