Chest bug or glitch

[XxcarterxX]

In survival games after the update came out, I noticed a bug or glitch that people have been using to their advantage. The chests in sg are filled and if you take something out and open up the chest again, the same things are there. People use this to their advantage by taking diamonds and making all diamond armour creating diamond sword and other weapons. Please fix so the games can be fair thanks!
