[BUG] Docks does not increase food per grain
I'm a calling this a bug even though the description does say "+5►+5". This is not reasonable!
My city has a Pier with +5 food per grain.
It is building Garden to yield +15 food per grain.
Docks requires a lot of Production for the small amount of reward of a Gildar increase.
Every time I've seem Docks it has always said "+5►+5". Why is this even said if it provides no benefit?
