This us cool, but please don't repeat the countries we already know too soon. It gets boring very soon when it asks you in a loop 4 countries you've traveled to

This us cool, but please don't repeat the countries we already know too soon. It gets boring very soon when it asks you in a loop 4 countries you've traveled to and you know exactly where they are! Edit: OK I suspect there's a clear bug, because over the first 15 country or so, the only one I didn't know how to place (East Timor) hasn't been asked to me again after like 20 times asking me stupid thing like Greece and Algeria in a loop.
