Hello, Mojang!

While I was on my realm, I saw this big chunk gap. I was confused But when I placed blocks in the chunk gap. It seem to turned normal. I think when I teleported to a certain place, then I teleported to where I founded the chunk gap. My friend didn’t see the thing, but I did. It was a big square, to be honest. Yeah. I didn’t understand where this came from.
