so a week ago, my minecraft world was perfectly fine, up on til a couple days later when i noticed cracks and the world almost sinking, it was like a meteorite hit the ground and it wasn't just one instance or even one island, it was the entire map and when i tried to go to another island it was the exact same and to note the holes are mine shaped or tnt shaped (pretty weird) if anyone knows what's the cause of this or just the reason i would be very happy to get a response (thank you) and also if you are wanting proof i can post it. - thank you, again : )
