Hi Palary,
again, your changes do not solve the problem. https://www.openstreetmap.org/way/736814424 needs a `layer=*`. https://www.openstreetmap.org/way/119940681/history has a `building:levels=2`which contradicts with `level=1` on https://www.openstreetmap.org/way/736814424.
Please, stop working on this challenge for now and talk with your instructor.
Take care,
skyper
