Describe the bug
Invasions start off on days 7, 14, and 21, but then they add one for every four invasions, so 29, 36, 43, 50, (+1) 58, 65, 72, 79, (+1) 87, 94, 101, 108, etc. (Invasions occur every floor(7.25x)th night)

To Reproduce
Steps to reproduce the behavior:

1. Wait until day 27
2. Observe there is no invasion on the night of day 28.
3. Observe there is an invasion on the night of day 29.
4. Wait long enough to see a pattern.

Expected behavior
Invasions should occur every 7 days.

Additional context
I believe it's something wonky about HW Invasions' night checking thing, but I couldn't find the source of the bug.

we still need to look at this, does it still happen with the 9 day change?
