I was doing some tests for the freight plane pak when I found this. Is this supposed to be a graphical bug or a not described feature? It seems Simutrans supports nuit américaine (http://en.wikipedia.org/wiki/Day_for_night)...I'm using v100.1-2052 Oct 2 2008 + pak64
Vilvoh - just bright stars and your good eye ;) There are no clouds in th Simutrans world ...
