I have just tried to select the location of my Holding Corporation and opted for a location in South-West Germany.
Unfortunately, the Selected location claims to be Switzerland, while the Rollover at the same position correctly identifies it as Germany.
Cities where this bug is present include Freiburg, Tuttlingen, Ravensburg, Friedrichshafen, Leutkirch and Wangen im Allgäu.
While testing which locations work, I’ve also noticed that the northern part of Karlsruhe shows up as being in France, Saarbrücken and Cologne show up as Luxembourg and Malmö (Sweden) shows up as Germany.
Therefore it seems to be a bug in the processing of the Selected location, somehow using a wrong value (to the south west).
