Hello, i have a problem on my single player mod. When im trying to destroy a block on a different world that i travel to like gallifrey or skaro, the block just re appears. And also when im trying to hurt a mob on that world they're motion are in slow motion. Im currently using ForgeOptifine on my launcher. My pc isnt that bad and i dont know what to do. I also install other mods in my single player. But even when i remove those mods and do the exact same thing. The result is just the same. (sorry for bad english btw) thank you for those who reply to my post
