Creeper blew up part of a double chest.

One double chest was left with a single chest remaining. 

Remaining chests were usable.

Part of double chest that was destroyed, remained as an "invisible" hitbox.

Attempting to place new chest at position crashes server.

Crash reverts server back to last saved state of player causing crash. Deleting potentially hours of work from other player.
