Cannot add piston head to piston

Stewart Davis shared this bug 13 months ago
Reported – Awaiting fix

I created a 30x20x1 trench in the voxel ground. I had used 4 groups of 5 stacked pistons to create a working pocket door with blast door blocks for a hangar on the planet. There was a lot of strange tension in the blast door blocks, and I know some voxel earth was just bleeding into the vertical space of the trench, so I removed a blast door block to remove the dirt obstructing smooth movement and the blast door and pistons caved into the trench. Before I did this the stacked 5-high pistons expanded and contracted fine, there was just a strange tension in the door blocks. (they vibrated a little, and some of the edges at piston boundaries weren't perfectly connected. I cleaned up the mess, removed *everything* from the trench, and outlined the 30x20x1 trench in light armor blocks, so I could visibly see any voxel encroachment. There was a little, but there is none at all now. I am now trying to build new pistons in the now completely clean trench and I cannot put a head on a piston on top of another piston anymore. Clicking 'Add Piston Head' on it does nothing. In none of the 30 blocks along the trench can I now add a second piston with a head on top of the bottom most piston. This previously worked, and I do not know why it does not now. I've gone along the walls to make sure there are no 'bits' of voxel, and no bits of broken steel in the adjacent blocks. I don't know how to illustrate this visual to attach an example, so I hope the words covered it. Let me know if I can do anything to help further troubleshoot this please. It's absolutely destroying my motivation to continue working on the world I've put a lot of time into. This is a MP SE server I run and play with one other player.

FWIW, if I cut about half a block's width of voxel earth out of the adjacent blocks to the piston [so it's effectively 2 blocks wide (1 center and half on each side)], I get piston heads. Is this intentional? Desirable? The piston can move with only 1 block wide, the first piston with a head can move freely in that single block wide trench.

Hello,


you could illustrate the visual by providing us with screenshots of the sitation or with a video of this (not)happening.

A blueprint of your contraption or preferrably a save file with the world could also help us.


Thanks for your cooperation and have a nice day,


Keen QA

I put a zip of the world here: https://1drv.ms/u/s!At5rrbK6TvMknaJJ6mcK7i8akxj39g?e=0hvXU6 It's PW protected. Where should I send the PW?

This is a brand new world I created solely to demonstrate this issue, this time in creative, though I found it in survival originally. It's completely reproducible, 100% of the time.


What you'll see in the pic is there are two pistons there, stacked one on top of the other. They are sandwiched between light armor block walls with a single block of air between the armor block walls, which contains the pistons. The lower piston gets a head when you put it down. The piston on top of it does not get a head. If you put a half block more air on each side of the piston (between the pistons and the armor blocks) it gets a head, and with that extra air gap, every one above that gets a head too.

I have the same issue as this guy. Did anyone find a solution/1E5030BD4EC1D7D71DA971328BF27C288DF91AD8 or just need a new game?

Hello!

Thank you for all the information. Stewart, I have managed to reproduce the issue with the test save file you provided, which was a huge help. I have now reported this internally and is awaiting a fix.

Kind Regards

Do you have an idea when that might be Laura?
