Darwin's Journey: Falmouth Port Mini-Expansion

Yes. You may place an achieved Objective face-down on an empty matching silver or golden spot to gain its reward; you may also place a face-up Objective on an open spot as a reserve, following the base-game rules. (Falmouth Port Rules, p. 2)

No. Neither of the rewards from these Objective locations gives end-game victory points. (Falmouth Port Rules, p. 2)

After achieving a golden Objective placed on your Falmouth Port board, you may replace an Explorer on an Island track with your Horse; after achieving a silver Objective there, you may replace your Ship with your special Ship. In either case, the upgraded token keeps the original token’s position, and the replaced token goes back in the box for the rest of the game. (Falmouth Port Rules, p. 2)

After upgrading an Explorer or Ship, you must place one of your Roof tiles face-up next to the completed Objective. On a later turn, after all your actions, you may activate an active Roof tile if you performed at least one matching Correspondence or Academy action that turn; spend 1–4 Coins to move its associated token 1–4 times, and activate each tile no more than once that turn. (Falmouth Port Rules, p. 2)

Yes. Once its Roof-tile movement ends, you may perform the action shown at the token’s stopping place, following the regular token-movement rules. With the Firelands Expansion, however, a token moving by Roof tile activation cannot interact with Adventure tokens. (Falmouth Port Rules, p. 2)
