Hey I know theres been looting due to the new "Hoppers" so i found a way to protect chests fully. All you do is put a locked chest under the chests your trying to protect and Wall-a a fully protected chest.

 

Do a screen shot of an example so people can see what it looks like

 

Yeah Ok.

 

You can also place locked furnaces underneath

 

Yeah anything you can lock under it

 

I know hidden chests under normal chest trick but for those who don't shoe them a pick I can't cos I don't have a computer ATM.
