Well, what I do is 1/19XX I retool my stuff, adjust pay rates for inflation, bank my money, and a few other things. I've noticed it's when I go from the safe back to the office I have them. I don't know if they're supposed to be the new model mails, announcing there is a new model for this and that, or if it's just a bug. At least that's what I've noticed after 3 years straight, is that it happens when I go from safe to office. Your results may vary.
