When I play in my world, after walking around 500 blocks (I'm not sure how many blocks it is an approach) an invisible barrier appears that does not allow me to advance, I have to leave the world and re-enter to be. It is able to move forward, but it is very annoying because it happens every time I enter the world and I start to walk a couple of minutes, the barrier appears that no longer allows me to advance, in addition if an item or a mob touches this "barrier" it freezes and starts to cool very fast
