Sun direction issue?

[RKING69]

When playing the game on maps in the northern hemisphere (ie; Germany), I've noticed that the sun is in the north and the shadows are on the south side of objects. Is this hard coded or is it possible to adjust an entry in a file to rotate everything (sun/shadows).

Thanks!

So, it seems the whole map world is rotated 180 deg, cause the sun comes up in the west, and sets in the east.
