So my friend gave me one of his worlds and all of a sudden when I load it up one day and there's signs for around a 1,000 block radius. I don't mean placed signs though, as in the ones that you just dropped. Reloading the world doesn't work, and even with my computer (Which is pretty good) it drops down to a insufferable FPS. Is there anything I can do to get rid of them, some mod that I can download that I can use to despawn them. (Because they won't despawn)
