If you search for Fuhrmannsweg, Arnstadt, you get the correct position, but the text "Fuhrmannsweg, Kleingartenanlage Weintrete e.V., Siegelbach, Arnstadt, Ilm-Kreis, Thuringia, 99310, Germany, Europe" you also get is wrong, because "Kleingartenanlage Weintrete e.V., Siegelbach" is added by mistake.

By the way: The "Kleingartenanlage Weintrete" is not located in Siegelbach, but near 50°49'40.8"N 10°56'15.5"E.
