MC-59474Sticky Pistons not correctly pulling back slime in a retractable setup
When using a sticky piston setup in which there is a retractable extender (two sticky pistons pushing/pulling a sticky piston and a slime block, see image attached) in some random cases the sticky piston will not retract, and will remain that way for that coordinate pair permanently. The images below show the bug in detail. What I have done here is set up 8 basic retractable extenders. I set a redstone torch in each pit, and a redstone torch activating the two back pistons, then removed them in order to reset the pistons back to their original setup. In 5 out of the 8 cases, it worked fine, but in 3 cases, the pistons did not correctly retract the slime block. this has been repeated on multiple worlds, and the issue stays on those 3 setups no matter how many trials are completed, while the other piston setups continue to work correctly.
Edit for newer version In all the latest releases, the slime does not pull back at all. Every single piston set up does not work correctly.
Another setup is shown in MC-85581.

Is this still an issue in the most recent versions (i.e. 1.10.2, or 16w42a) of Minecraft?

Duplicate of MC-59474.
Please do not mark unreleased versions (anything starting with "Future Version") as affected. You don't have access to them yet.
Very sorry. I was struggling to assign a version, since the bug only appears to get worse in newer snapshots (the most recent where no slime blocks retract at all). It appears you already removed that tag, so I will be sure not to do so again.
I can still see this issue in 1.8.1 as well as 1.8.2pre6.
Can confirm for 1.12
Can confirm for 1.12.2, however it seems to never happen when the two pistons retracting the piston and slime blocks are facing to negative z aka north. For all other directions, the bug happens always.
[Mod] NeunEinser: ticket is yours now. Please update it accordingly. Thanks!
Can confirm for 17w43b
[Mod] NeunEinser tickets is already yours in case you didn't notice. You can update it yourself now.
Affects 1.13-pre6
See the screenshot "Piston slime bug - Recap" where I've laid 4 possibilities for each direction. (Red ones are the broken ones).
Can confirm for both 1.14.4 and 19w44a. I've also created a test map that displays the glitch that I could share.
Still present in 1.15 and 1.15.1 Pre-release 1.
I,ve uploaded two videos where I realized of an exception (see videos attached). When a piston is powered directly with a redstone torch (that torch is on the previous block), piston will pull back the slime block when the torch is removed. But if the piston is powered by redstone dust (it doesn't matter what power that redstone dust) the piston won´t pull back the slime block when redstone is powered off.
Please, if I don't explain myself well, see de videos attached. I know my english is quite bad.
Confirmed in 1.16.1 and 20w29a.
Confirmed for 1.18.1. I'll also include a world displaying the issue since it seems to occur only in certain directions. There's probably even more directions but I think the world should be good enough.
Confirmed for both 1.19.2 and 22w44a.
Seems this is fixed with the experimental redstone in 24w33a using the test world I shared but I guess that could change since it is experimental. Thought I'd leave a comment about it though!
Thanks for the comment! In that case, I will mark this report as fixed with the experiment enabled, by using a label.
