Do colonies, buildings or wonders covered or replaced by newer cards still score at game end?
The designers confirmed that only the visible cards score, and the rulebook's Game end section concerns the final board.
No. Only the top card of each slot on your Player Board scores. A card that is covered, replaced or removed is out of play, so it never scores. Some players keep covered cards tucked under the new one to look through, but those never score either.
