Here's a new one? In the past few days I earned two achievement I should not have. A few days ago, I purposely set out to earn Metroplex - completely surround my Government Plaza with districts or wonders I earn at the start of the turn. I had three of those hexes filled when the badge popped up. Then yesterday, I was playing Tamar when the Holy Righteous Queen Tamar popped up. That's for having every city-state in the game following my founded religion. At the time, exactly one followed it. Kinda takes the fun out of it. And with all the other bugs and annoyances, that's one of the main reasons I still play the game.
