Messina 1347

No — a citizen rescued from a hex that has a plague cube must be placed in quarantine immediately, even if you remove the plague later that same turn (p. 8).

Citizens in quarantine cannot be used to repopulate Messina (they stay in quarantine for two rounds) (p. 13), but a citizen that is in a workshop can be sent to repopulate a neighborhood (p. 12–13).

You gain rats if plague cubes remain after you spend fire tokens on a hex and also whenever a plague cube is added to a neighborhood you repopulated (p. 8, p. 13). At game end each rat moves you back on the popularity register and then you lose points according to the rat-penalty table (p. 17).

An upgraded overseer provides extra activations when it advances; if an effect both upgrades and then advances that overseer (for example a church-register space), the upgraded ability applies during that advance (p. 11, p. 14).

No — the plague cube on a boat is not considered adjacent to any hex, dock, or other boat, so a major fire token used on a boat cannot reach an additional adjacent cube (though you may use a major fire token as a regular fire token) (p. 9).

Yes — when you advance to the indicated city-register space you may take the action depicted on any hex in Messina even if that hex is blocked by a standing figure, but this permission does not apply to docks (p. 14).
