The blocks are placed and destroyed correctly when away from the chests. However, this world did not suffer noticeable lag in earlier versions of the game.
I have waited 10+ minutes before reloading the game. I have linked to a video where I place 3 blocks and remove another 3, then wait over 3 minutes before reloading the game.
