After showing the animation for removing the dirt an 'air' block appears at the place of the dirt block as per usual. However, when I walk into the space my character starts glitching(moving rapidly back and forth by an inch or so) and after a couple of seconds starts taking suffocating damage. The block can then be removed. However, if I attempt to remove the block before I glitch myself into it, nothing happens, just as if it's an air block. This bug occurred while removing a large amount(around 60 blocks or so) with a Efficiency 4 Diamond Shovel, which makes the removal very very fast and I presume the speed of removal is why the bug occurs. It happened twice in a row performing the same action in different spots and does not seem to happen with other materials/tools.
