As you can see, the Central Asia map (Ásia Central here) is the end of the alphabetical order. I assume it’s because of the diacritic in the first A.
Also, some map name translations are weird: Araucania becomes Araucária (it should be Araucânia), Manchuria becomes Nordeste da China [Northeast China] (It should be Manchúria), and Horn becomes Sudeste Africano [Southeast Africa] (it should be Chifre or even Chifre da África). There are probably more weird translations but I can’t remember any right now.
Also, I ran into the House of Wettin in Portugal in a game, but they’re not listed in the available settlements.
