MC-34201Double extending pistons act differently at different Y values. (As far as I can tell)
Long story short(ish), I remade CNB's famous compact 3x3 piston door so that it is the same compactness and works in 1.5. I have a super flat world made of Cyan clay, where the ground is at Y=60, and when I first made the door, it worked fine (above ground, so I had extra space, the bottom piston is located at Y =61) . But when I tried to move it underground, i noticed the pistons were acting differently. I've narrowed it down to the part pictured in the images (i've made a simple clock to keep them running so you can see which piston is extending). So when the door was above ground, the TOP piston extends and retracts quickly, leaving the block on it above it, which is the basis behind closing the door.
What actually happened was below ground (Bottom piston at Y=57), the BOTTOM piston extends, which pushes the top piston up, and renders my door useless
Steps to Reproduce:
1. Simple clock, into a monostable circuit, then feed that into a diamond of blocks.
2. redstone in the center of the diamond, torch opposite the input from monostable circuit, and a redstone above the block above the torch
3. activate clock.
4. rinse and repeat at different Y coordinates.

That's very weird, I just tested at Y=58, and the TOP piston extends... I'll continue testing
Tested at Y=56, BOTTOM piston extends. so it seems Y=57 is the crucial height
Okay, now i'm doubting myself... tested at Y=65 and they both extend/retract in rapid succession (bottom exends, bottom retracts top extends, top retracts)
Nevermind... I just built it wrong, but the bottom one is extending at Y=65
"Nevermind" means that ticket can be closed ?
No, that was never mind to my previous comment. sorry.
Is this not a duplicate of
MC-29430btw... ignore my comment in that bug. I was thinking of an old formula redstone use to use. I can't figure out the reasoning now as to why location makes any difference. My screenshots in the bug do fix the issue, though not as compact as your setup
At least related.
MC-29430is similar, except both pistons aren't extending, that was an error with me building it during later testing. only one piston extends, the problem is whether it is the top or bottom.Also, compactness is kind of important in an compact 3x3 door
I have yet to find a work around, and it seems to be only a few specific coordinates (I got it working at a different location, with the same Y value), Perhaps it is related to MC-11193 in some weird way? Still an annoying bug as that's the most convenient place to put the door. I also tested it on a friends server, in four different locations, one of them extended bottom piston, the other three acted as expected.
Sorry, I am unable to test this on newer versions due to loss of my pc.
Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases. If this has been done, we can reopen the issue.
Keep in mind that the "Resolved"-Status on this ticket just means "Answered", and that we are waiting for further information on whether this issue still exists or not. We will reopen it as soon as the requested information has been deliviered.
No response for over a year.
