            <title>[MC-631] Duplicating/deleting blocks</title>
                <link>https://bugs.mojang.com/browse/MC-631</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;With the setup in this video: &lt;a href=&quot;http://www.youtube.com/watch?v=YVms3avJ79Y&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://www.youtube.com/watch?v=YVms3avJ79Y&lt;/a&gt;&lt;br/&gt;
You are able to delete and duplicate blocks, when placing it on the pulsing sticky piston. The duplicated block however is some kind of ghost block, since it can&apos;t be mined (does not drop an item), will disappear when updated or when the world is reloaded.&lt;/p&gt;</description>

As you can see from the attached screenshot this is not just a visual glitch. Although the blocks cannot be mined, you can stand on them and cannot move through them.&lt;/p&gt;</comment>

Sticky Pistons (&lt;em&gt;hooked up to an armor stand timer with soul sand&lt;/em&gt;) are duplicating Chiseled Stone, and pushing out the duplicates. &lt;br/&gt;
Logging out of the server and back in will reset it, so it still appears to be client side.&lt;/p&gt;</comment>

If so, please &lt;em&gt;update the affected versions&lt;/em&gt; 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.&lt;/p&gt;

&lt;p&gt;Keep in mind that the &quot;Resolved&quot;-Status on this ticket just means &quot;Answered&quot;, 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.&lt;/p&gt;</comment>
