Sorry for making the video password protected. I have updated it so that anyone with the link can view it. Also I am playing on v1.17.2, the bug you were referencing were vertical pistons, this bug is dealing with vertical pistons(sorry for not clearing that up). To reproduce the bug you need a extended sticky piston to retract a block that has a gravity block above it. Pre 1.17 the block would fall but in 1.17.2 the block breaks. Finally, I use anvils in the clip but I tested it with the other blocks and they also break. Hope this gets resolved!
