I have only played World Warfare for about a week or so and I am still discovering how everything in the game works. For some reason all of my buildings lost a bit of health and I cannot find any reason for it. I just logged on, played a bit, and when upgraded my city and clicked on some buildings, they all lost about 1 or 2 health. And not just my capital city. All my villages, resource/military zones, even other cities too! Does anyone know the reason for this? Not very important to know the answer but I find it very odd that it happened. Maybe it's a bug? Thanks for giving me an answer if you do!
