I was in my world, when I wanted to get all of the new wolf type in the preview, I picked off a wolf spawn egg, and started spawning a wolf in a Jungle. But when I moved a farther, and loaded new chunks, when they generated there was a 10-20 sec moment when they bugged out, and when I spawned a wolf in it it deleted blocks, even water around me. And it was a vanilla world , I dont had addons in it. But then it resetted everything! Placed back all the blocks.
