I play multiplayer with my friend, only 2 of us. At the first season everything is very good but when the summer come, my friend has some problem. Each time he opens a chest, it takes him about 5 mins to appear items inside, or when he moves to another screen, it take nearly 10 mins to move again. I'm the host and i still play normally. First i think about my internet but it haven't changed anything since i start the game, so can it be game problems? If that so, can sb help me to fix it? Thanks everyone.
