Dropoff zone full, dishes not being cleaned.

I started up a new game with build 18. Ran into some similar problems but did notice some confirmation of a theory.

1 - Sickness still a thing, nurses not being used.
2 - Starting on day 5, it skipped every other day, that is no day 6, 8, or 10. None of the staff stayed the night in the school. So kind of the opposite of what I had noticed in my previous post.
3 - Dishes still being left uncleaned in the cafeteria.

One thing that might help with the finances - Computers are very expensive. One computer uses about $100 in electricity! That seems pretty high. Anyway I cut back on my computer lab when I saw that. It would be nice to know what the costs are for various items. I notice my water bill is also very high, so I am not sure how much I pay a month for toilets and sinks. I cant say whether these are balanced or not but it would save a lot of frustration if the costs were more transparent. The financial breakdown form is helpful.
