Here is a picture of what I think is a bug in Golden Ages. London has just completed the colossus and that spurred a golden age. However, I am not getting any bonus production or bonus commerce except on the center tile. In the help, it does not say that the bonus for golden ages depend on government type or anything else like that. I also would expect the Colossus and golden age commerce bonuses to stack.
All of the mined grasslands are bonus grasslands so normally they produce 2 shields.
Is this a bug?
