Placing/breaking blocks are delayed:

When trying to quick build, my blocks will dissapear and return back to my inventory, if I’m building too fast. This also occurs when breaking things. Usually when I’m trying to destroy grass, torches, etc., they will sometimes get destroyed and return a second after. I believe this is because the items/blocks are taking half a second to register, making it impossible to work at a faster pace. Please fix this because it has been occurring to me and my friends, and it makes it a lot harder to do things. Thanks.
