So whilst playing Minecraft on the latest snapshot I encounter a problem to do with the world generation, simply after walking around for about 30 seconds I come to basicly chunk errors, the chunks just don't load until I get around 3-4 blocks away from them and the only way to refresh the chunks is to do F3+A at the same time, the only downside to this is that I find myself doing this action every 30 seconds and its really annoying
