So this is my best survival on mobile, and I was doing good. I try to go in, and it says can not open world, and I can't go and try again until I get out of Minecraft and get back in. So 30 minutes later, I got back into the world, and I die immediately. It says that my bed was destroyed. I was confused by this, so I go look for my house, then I see it. HUGE chunks taken out of the world, that go all the way down to the end of the world. I'm not really sure what this is, but all I know is it ruined this survival
