(R&F, all DLCs) posted this in the bug forum, but it's not as active as this one. plus, perhaps it's not a bug and just the way it's supposed to work? would like to know before i invest more time into the game, haha.
playing as mongolia (warlord difficulty - first game and haven't played since civ4). just got the conservation civic, but none of my old growth forests are adding their supposed +2 appeal. i've skipped ahead another turn, and still nothing. that said, i am ahead of all other AI civs, so the official game-wide "modern era" hasn't been declared yet (tho all my cities, units and roads are now graphically "modern" era) - does the added appeal effect need to wait until then?
