            <title>[MC-4089] Piston Disappears, Turns Invincible</title>
                <link>https://bugs.mojang.com/browse/MC-4089</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;I went down to my skeleton spawner. It uses a couple of sticky pistons to crush skeletons. But, my game crashed. It had a green line of static running down from the top left corner to the middle of the bottom of the screen. I saved, and restarted minecraft. I went back about 24 hours later, and i tried to use my spawner to get some bones. But, the blocks of cobble wouldn&apos;t move. They stayed extended. So, I went in the back, checked my redstone circuit. It was fine. I checked my pistons, and  they were gone. I could walk through them, but I couldn&apos;t destroy them. I took some pictures, and tried to place a block in the space the piston occupied. The block was placed, and then it disappeared, along with the piston. &lt;/p&gt;

&lt;p&gt;&amp;#8212;&lt;/p&gt;

&lt;p&gt;EDIT:&lt;/p&gt;

&lt;p&gt;The pistons are gone again. This time, no crash, and no out of date java. While I&apos;ll keep my old report, I&apos;m now very confused. &lt;/p&gt;</description>

The pistons run on an repeating redstone current, they run forever. The push a single block of cobble each. Not sure why they disappear, but they are ruining my grinder. &lt;/p&gt;</comment>

Nothing helped. my pistons disappeared again. I&apos;m glad slimes spawn in swamps, otherwise, this would get quite annoying. &lt;/p&gt;</comment>
