I don't believe I've seen a thread around here about this, or anywhere for that matter, so... Has any of you also noticed that under a republic or democracy celebrating cities will generate an extra shield every turn? I first noticed this years ago when my large trade cities would still manage to pop a caravan every 50 turns, even though they had low production and generated no extra shields after unit support. This has the funny side effect of screwing up your city menu predictions. Let's say your city generates 9 shields and you're building a caravan. The menu will say it'll take 6 turns, but if the city is celebrating throughout, it will actually take 5 because every turn a shield will be added.
