I have sugar, and I was trying to trade with another with sugar.
When I hover the mouse over my sugar icon, it says: +3% population, +1 happiness (same as in the help page). But over his sugar icon it has the extra +5% land.
So is the +5% land a typo, or is it a new effect? If it is new then don't older nations get it? (His nation is only 23 days old).
