That happens to me as well, and I have a similar clock speed to Kelsey at 2.1GHz. It seems to happen the more manual blocks that are in the game and its very annoying
pretty annoying if you ask me, plus why does it then work when there is a block above you?
i dont get why this is an intended feature with chests. Surely, it should only be with soulsand.
I dont think faulty mice are the problem, in my opinion, its the lag produced when placing/removing a block as I have experienced lag while doing it and during that lag, 2 or more blocks have been placed/removed. And this becomes more apparent the more blocks that are placed in the game
