I was playing on a superflat world doing some red stone when I tried retracting the sticky pistons they did not pull the block above so I tried the same thing above ground and it pulled the block with ease so I assumed it was a glitch so I restarted my console and the same thing happened the block in question was cyan terracotta which is movable this world has holiday creator features and default game options in addition the piston will pull all blocks left right and up but when it retracts that's the only position it's in where it won retract the block as well (this only happens if the piston is facing up and at y level 1). Whoever reads this thank you for giving your time up for this I hope you have a good rest of your day or night.
