Everdell Duo

You may play cards from your hand, from Meadow cards by the Sun token, or from Meadow cards by the Moon token; when you play a Meadow card fully resolve it and then replenish the Meadow (rulebook pp.5–6).

No — when you Pick a Card you may draw from the deck or take any card from the Meadow, even if the Sun or Moon is not near it, then replenish the Meadow (rulebook p.6).

Production (green) cards activate immediately when you play them and again at the beginning of Spring and Autumn (rulebook pp.6–7).

An Occupied token lets you play a Critter for 0 berries by placing the token on a Construction of the same color (one Occupied token per color); you may choose to use an Occupied token even if another discount (e.g., Inn or River) is available (rulebook p.5).

No — you may not perform an action that would require moving a token once that token has reached the end of its path, so you cannot take a Place a Worker action if it would move the Sun (or Moon) token when that token is already at the end (rulebook p.4).

The game ends immediately when both the Sun and Moon tokens reach the end of the track in Autumn; score cards, purple bonuses, point tokens, and Events, and resolve ties using (1) most Events, (2) most leftover resources, (3) most cards in city, then (4) most cards in hand (rulebook p.7).
