We had a support ticket that two counties in Vietnam belonged to the wrong region. Our data was from early 2021 and OSM has been updated since then. I will run an update today.
The scripts I have didn't find any affected challenges, and I would assume there aren't any either. But all counties will be renamed. I assume it's more proper spellings.
