Sticky pistons are bugging out completely, some of them are not receiving any redstone signal at all. But the main problem right now is the sticky pistons are literally not doing their job, they won't grab the blocks and hold on to them. I believe we should get a redstone update and bring back the old redstone algorithm, like back when 4J Studios was a thing in Minecraft, because none of the contraptions that I made before work and there's no way to do any minor modifications and it takes up a lot of space in my world, especially when I'm trying to keep it hidden.
Video proof of sticky pistons not working: https://youtu.be/O_iL-hfOn6k
In the video, the upper right sticky piston sometimes does not pull the other piston because that piston is already extended when the right-side sticky piston begins to retract. The extension and retraction happen in the same tick, so which happens first is random. This is intended behavior in Bedrock Edition: see MCPE-16371.
