Hi! Thanks again for your contributions, and also for the very descriptive changeset comment!

The house you added looks well-traced to me. My only suggestion would be to press "Q" to square up the angles a bit after drawing the outline - and feel free to add more details to the address (like zip code and city) though just the housenumber and street is definitely better than nothing!

In this case, it is true that the surrounding buildings are the ones that are offset, so you've done nothing wrong! The geometry of these buildings is mostly untouched since their original import 11 years ago. It's standard practice here to use the Bing imagery for alignment, as you have correctly done.

Happy mapping!
