Black Belt
I don't know if this one has been brought to attention with 1.16:
I controlled Odessa as the Ottoman, and it was the only city in the labeled Black sea region. However, I still failed the 2nd UHV. I tried to WB and control the Russian city (which was not in the Black Sea region) and still failed.
For the UHV, you need to cover every tile on the Black Sea coast with your culture.
