It takes a truly odd event to bring me out of lurker mode to post something, but this one is really making me scratch my head. Game is BTS 3.17, BUG mod and Blue Marble Terrain. I am Korea on a Hemispheres map, difficulty is Noble. Here is Pusan in 580AD, building a granary... and a shot of the city screen.. ok, hit end turn, and in 595AD... I have no idea what happened to make a wonder just appear like that. In fact, when I was playing the game, I didn't even notice this, as I was monitoring other cities, waiting for Pusan to finish its granary. As you can imagine, I was quite surprised to see this in 610AD... I went back to the earliest auto save, which was 580AD to take these screenshots. So, what happened here? Is it a bug? I thought it might be related to the BUG mod or Blue Marble, but to test this I uninstalled both and loaded the save, and the Parthenon still builds itself. Also, as these are both graphical mods and do nothing to the game rules, it seems unlikely that either is the cause. I guess it could have still been one of them, but I'm pretty sure it's not. edit: screenshots linking properly now Here is the save from 580AD if anyone wants to take a look at it.
