Conditional slots 8 for 4 species — time of day, weather, radio and other switches

The game keeps these slots separate from the base ones. Condition sets exclude each other (it cannot be morning and night at once), and the source does not say whether a condition adds a slot or replaces the whole table — so we list them row by row instead of adding them to the rate on the tile.

	at night	18–24	90%
	in the morning	18–24	90%

Quagsire	in the morning	22	4%
