Autocorrection :)

I found it, but too late. It's a new JOSM 'smartness', autoroccection. Should be bot=yes

Hi @Andyb_66, what do you think should be in the comment? There is an article in Wiki, url is in changeset tag. All changesets since the initial import has been completed are updates downloaded from cadastre (RUIAN)
Thank you for yours idea(s)

OK, let's for example:
:All changes from Czech cadastre since last update"? Because of I actually don't know what is in the changeset; I check suspicios changes reported by the bor itself - newest report is available https://mapserv.poloha.net/~osmimport/data.html (in Czech only, it's just for me to help me to find suspicious changes). The Cadastre is not 100% error free.
