The Seasons have some impossible values.
- Given that Paths cannot cross the meridian and There must be at least one route connecting the two forest entrances., the Heart must always be connected to 2 (or 3) paths, so the Season can never be 1 (Spring). It must be at least 2.
- Also, it can never be over 18 since A given location [including the Heart] cannot have more than 3 connected paths.
