I've had this happen to me in singeplayer and multiplayer now, and although it isn't exactly a bug, I feel like this can't be the developers' intention: A prolonged war causes War Weariness to get high War Weariness eventually causes such low Amenities in all cities that you get -60% to all yields Having -60% gold in all cities means you're going to have a gold deficit. If you don't have a large treasury saved up to avoid bankruptcy, you will soon be doomed. Once bankruptcy sets in and starts reducing your Amenities, you are now in a death spiral. Even when the war ends and War Weariness goes away, the Amenity reduction from bankruptcy keeps you at -60% gold (and everything else) in all cities. It's nearly impossible to get out of this situation. If you look at the attached image, you can see that even if I deleted ALL of my units, the expenses from my cities alone is enough to keep me in the red. This is with a Merchant Republic, and all possible gold bonus policies taken.
