Just fired up the game first time today and having the same problem. the "saving" -text doesn't disappear ever and when I try to quit the game, it says to wait for the saving. I'm playing offline I think? Steam is online, but I haven't logged into anything in the game.
Also, is it intentional that the numbad keys 1,3, 7 and 9 don't work for diagonal movement? I seem to remember them working on the old "alpha" -version of the game, so what's up?
