I started a new game yesterday. Built two new towns, captured another one.. suddenly these weird messages pops up that unit so-and-so has been trained in town so-and-so. Not just once, but almost once per town, every turn.
Another bug I just recalled is that sometimes when i capture a town, in the view it's still the other empire's. With the troops still intact, but when I save/load it's no longer so..it's mine all mine.
