Yesterday, I tried to walk past the world border, then I saw there was a invisible wall on X/Z = 29.999.999,000 blocks. I used ender pearls to go through, making the player lose precision, in a way that he can't walk, jump, fly, nor anything else. Just using chat. The only way to escape was teleporting inside the world border. When you sprint on X/Z = 29.999.999,000, but with View Bobbing on, the First Person view hand keeps animating, because probably that second wall is for the most part "The Precision Loss". The game does not crash that way.
