Played a game just now where in the ancient era, I got an event where I could choose between several options, one of them giving influence per population on my first outpost. However, my influence per turn did not change at all, and stayed at 1, depsite having 3 population in the outpost. It wasn't just the yield indicator that was wrong, but when the turn ticked over, there actually was just 1 influence extra in my pool, instead of 7 extra influence
