Bugged Pistons

Build the structure on picture #1

Place a redstone block like picture #2

Put a block on top of the piston like picture #3

Break the Block like picture #4

It shouldnt be activated

same works on droppers

Break the redstone block like picture #5

You will get an activated piston without redstone
