When I try to set up these pistons pushing sand up, it works sometimes, and other times it pulls in the sand, pushes the sand up, it falls back down, gets pushed back out, then back in until it finally stays up, sometimes it gets stuck trying to push sand up over and over until it finally works and stays up. It's very unpredictable. I've tried different delays with repeaters and it doesn't seem to change the consistency of it. Happens with other redstone contraptions as well but this is the one that I'm dealing with right now.

I know there's several other reported issues that are kind of the same thing, but they all get marked as "resolved" but the bug is still there so I don't understand why they keep getting marked as resolved.

Also I know it's not "working as intended" because redstone logic should not be random, sometimes working and sometimes not.
