--- Comment #17 from fjfrackiewicz@gmail.com --- So now the question remains if this is a Wine bug, a bug within the application, or a GOG-version bug.
Thank Bruno for finding out that one line in the debug text.
As for me, I will run this game on a Windows machine to see what it does when installed there and to see if that nw2 folder shows up.
