I'm thinking that a lot of gold traces on boards are so thin, that if left in solution for over 24 hours it dissolves so much of the copper that the gold almost vanishes, meaning there is a very thin amount of gold over top of a heavier layer of copper. I also think that much of the gold flakes still swirling around is still mostly copper ...
