Bills delivered on any weekday

Finally! For quite some time I've insisted that som of my homes got their bills delivered on other days than Mondays. It felt like most simmers doubted it could actually be true, and I could not prove anything. Until today!

Bills delivered on a Wednesday at 10 AM. This lot is in Brindleton Bay.

I'm now taking notes at every single bills delivery to check that the amount charged is reasonable, and that's also a good opportunity to check what day they are delivered.

My theory is that bills are delivered after 7 days, regardless of weekday. If you start a new house day 1 will probably always be a Monday, meaning the 7th day will also be a Monday. So Mondays are naturally the most common. But I play rotationally, and I think it would be weird if a household played only on Mondays would get new bills every day they are played, while a house played 6 days a week (all days except Monday) should never get any bills.

I think the game adds a bulk of costs to the bills at a set hour every day a house is actively played, and also counts how many days this was done. When it was done 7 times, bills will be delivered the following day (probably skipping Sundays, though...). This will probably be easier to track once the June 2nd patch gives us split bills and we can see how the bills grow before they get delivered.
