BLOWING UP EREBOR IS POSSIBLE

So I created a minecraft realm called Erebor on creative mode and my brother decided to get a bunch of tnt mine carts and set them off and when they blew up, everything froze and I mean EVERYTHING. The whole server just stopped. We had to shut off the Wii U and reboot it to play again so I was thinking "lucky I saved five minutes ago." Well we got on to the game and the realm didn't exist. At all. His tnt had erased a whole server.

He blew up Erebor.

HE BLEW UP EREBOR.

Okay rant over sorry.
