Hello together,
I found this strange node:
https://www.openstreetmap.org/node/11607656634
It is located in Germany but addr:country=CZ. Some other tags are suspiciouse too.

@Kocián Šimon: Can you explain the content of addr:country and addr:city to me?

@t_ja: If you intended to fully revert this changeset, why did you skip this object?
