Keep having the game crash (latest free version) after a couple hours. I think it's a matter of using up memory. I have 16 gb of ram, but a quad core processor. This happens in longer play sessions, so stopping after an hour or two doesn't prevents it, and is something to help make sure I don't spend all night playing. I'm new to this site so dubious about buying things with new sites but will definitely purchase on steam and buy a few copies as gifts.
It's worth mentioning the autosave is a pretty great feature. It helps reset the day in case of crash. Restarting the computer and then restarting the game everything works again.
Also found out about the game through the Spiffing Brit channel. Great work all around.
