Seasons

Each settlement goes 3 cycling seasons:

Drizzle lasts 6:00 minutes. Crops are planted and positive Forest Mysteries are active.
Clearance lasts 4:15 minutes. Crops are harvested.
Storm lasts 1:40 minutes. Crops that are not harvested die and negative Forest Mysteries are active. Traders will not arrive. If Blightroot is present it will attempt to corrupt the Ancient Hearth.

Forest Mysteries

Forest Mysteries are generated at the start of each game, based on the map’s difficulty and biome. Some effects are simple modifiers influencing production, lowering speed or destroying buildings, but some are based on your villagers' needs. For example: Hailstorm can kill villagers during the Storm, but if they have a home, they are safe.
