Duplication glitch using chest and glass.

How to reproduce:

1- You place a chest down, and build 8 blocks of glass around it.
2- Put the items you want to duplicate in the chest.
3- Save and quit the game and rejoin.
4- Break all the glass blocks around the chest until you reach the final glass block, start mining the glass block and force quit the game just before breaking the final glass block. You can then rejoin and will find that the items have duplicated.
