I'm using World Map visualization and for some perverted reason, Crimea is highlighted as a part of Russia. It should be highlighted as a part of UA region, since it is a part of ISO 3166-2:UA, here's a relevant excerpt from SAP support
ISO 3166-2:RU contains no codes for the Russian-administered 'Republic of Crimea' and the Federal City of Sevastopol, which are internationally recognized as part of Ukraine. Crimea is a region of Ukraine and its code is UA-43 in the ISO 3166-2:UA.
Considering that Metabase uses ISO Alpha2 codes to display regional data on the map, this is a bug, and also outrageous.
I'm running v.0.41.4, and you can reproduce this by visualizing
SELECT * FROM UNNEST ARRAY['UA', 'RU'],ARRAY[2, 1]) on a world map.
Please fix this ASAP.
