I've never had an issue with the game.
I've also never used older version saves (says not to, so I didn't), nor have I ever used a mod (introduces too many variables that the Game Developers can't/shouldn't resolve).
There are walkthroughs on many forums, and at the devs website. This forum has a fine search function, and the dev site has live help, although I've not needed it because of the walkthroughs/stickys/forum.
Amazing what you can accomplish if you read, learn, and pay attention.
DarkCookie has done an amazing job, does actually update fairly regularly, and pays attention to details.
He has, however, strayed a bit from the core goals of the game, but that will be fixed later in the cycle(s).
It's playable, free, and is only at a small fraction of the complete game so far. Amazing work.
