I am playing Minecraft when the block I was mining (In the first case Cobblestone but every other block does this too) reappeared after I mined it, I tried to mine it again but it came back. After some time the item would finally drop.
What I expected to happen was...:
The block I was mining to drop and then allow me to pick it up.
What actually happened was...:
It reappeared regardless of how many times I tried to mine it, before eventually dropping after some time.
Steps to Reproduce:
1. Mine any block with any tool.
2. It will disappear for a split second then reappear.
