I play on my server and in my house I found a creeper. It exploded, dealt no damage to me and it was like someone on a offline server came with speed nuker hack and destroyed your house. Still, playing 3 hours after that I FOUND BLOCKS FROM MY HOUSE 6 BIOMES AWAY FROM ITS ORIGINAL POSITION! It happened on my singepalyer server and I got sad about my redstone contraptions 4 stacks of lapis 2 stacks of gold and 20 diamonds and my FULLY ENCHANTED DIAMOND GEAR.

Steps to reproduce:
1. make a house.
2. It is supposed to be with size 7/7.
3. make it from acacia wood in a bay in a dark oak forest.
4. the creeper is supposed to spawn from the mine in the house.
5. you enter the house from the main door.
6. the creeper explodes and deals no damage, then the game crashes, and your house gets NUKED.
