Why aren't some of the German names accepted while others are? For example I tried Niedersachsen, but it didn't count as Lower Saxony, but Bayern counted as Bavaria. It took me a few more seconds to guess each of these because I had to translate them to English.
Thuringen works for Thuringia as well, but Nordrhein-Westfalen (North Rhine-Westphalia), Rheinland-Palatinate (Rhineland-Palatinate) and all Sachsens (Niedersachsen, Sachsen and Sachsen-Anhalt, for Lower Saxony, Saxony and Saxony-Anhalt) don’t work.
Also disappointed that German answers were not accepted. The only two I missed were Rheinland-Pfalz and Nordrhein-Westfalen, and that was only because I couldn't get the spelling right in English.
