This evening, I have been on a walk under lit stars, I lifted my eyes up to the sky… and suddenly, I realised I’m standing right on the North Pole - the Polaris star is right on the zenith! I never realized Czech country was streched to the pole in 15th century!
Well, seriously - this is a bug, but not too obvious and definitely not a major one. Developers just mapped North Celestial Pole to Zenith, which is okay… for the North Pole But for Czech country, the Celestial Pole is about 50 degrees above horizon… so is the Polaris star in Ursa Minor.
