I didn't have an issue at all with option 0. I leave that on all the time and never get any bugs at all. The bug that comes with me being unable to continue to the next day stems from the badge cheat that adds +5 badges. That's the only option that when I use, makes the game unplayable, so I've stopped using it. With the other options I don't really need it anyways.
The rest of the trainer is magnificent now, and I thank 0x90 for all of his hard work. Bravo!
It's in the editor, there's a mafia tab, try altering the loyalty and dissatisfaction.
