Really appreciate the feedback, I'll look into the item issue. Do you remember what you were trying to buy/the amount you had when trying to buy? The crashes aren't intentional unfortunately.
I'm going to start labeling features that aren't implemented yet, currently working on an update that does this. I should've done it before releasing.
btw, there's an auto save that occurs every time the time of day changes which should hopefully mean less progress loss.
Lots of really great suggestions here.
