I'm playing TA and have noticed this oddity. Early in the game, I got the event where all civs get a major economic boost and tax revenues go through the roof. I know that this is supposed to be a temporary situation, but in my current game, it has been going on endlessly for a huge number of turns, how many I don't know, but it has been much longer than I think it should. I've been running my economy at 100% with an 80% approval rating and an income of more than 2000 bc all the way through both the initial and the late colony rush and through the development of all of my planets and the formation of my starbase network and my star fleet. And the boom continues. This doesn't seem right. Anyone else have this happen?
