Invisible Block

I have created a block, an invisible block, you can go trough it, but you cannot break it or place other blocks on it's place.

I downloaded the map with the update suppression bug (https://www.youtube.com/watch?v=mzfLHNeqjuY) and what I expected to happen was create something levitating or something.

*What actually happened was that the game crashed, I logged back into the world and one of the pistons had it's bace missing. I destroyed the piston's head and I have created an invisible block or something.

Steps to Reproduce:
1. I wasn't actually able to reproduce the bug '-'
