Why does Russia unlock some others don't? British Virgin Islands should unlock Virgin Islands, Czechia should unlock Bohemia and Malaysia should unlock Malaya.

Edit:checked the source and the standalone "Virgin Islands" are the US Virgin Islands, that should be accepted.

Czechia now counts for Bohemia. USVI now counts for Virgin Islands.

Counting Malaysia for Malaya feels too much like defeating the purpose of the quiz being all nations that have ever participated, as other federations would have to count for all of the predecessors. Russia counting for the USSR is different because the USSR is a successor to the Russian Empire.

Ugh. Any chance "UK Virgin Islands" could be accepted for "British Virgin Islands?"

I know that's not exactly how it's represented in the Olympics but non Olympic-specific type-ins are accepted in other cases. When I tried "UK Virgin Islands" and it didn't take, I assumed I was remembering incorrectly and abandoned that entrant...

I would suggest allowing the name of the islands without the "Islands" part for some like Cook and Cayman

I considered it, but Jetpunk tends to require it for the Marshall and Solomon Islands, so I left it as is.
