            <title>[MC-5774] Blocks being constantly pushed by pistons turn invisible after some time</title>
                <link>https://bugs.mojang.com/browse/MC-5774</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;Build the attached setup, place a redstone block between the pistons and wait a few seconds. Alternatively kill yourself (/kill), fly away and come back etc. (same steps as to reproduce &lt;a href=&quot;https://bugs.mojang.com/browse/MC-177&quot; title=&quot;Clocked piston arm turns invisible when exiting game/dying/etc.&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MC-177&quot;&gt;&lt;del&gt;MC-177&lt;/del&gt;&lt;/a&gt;)&lt;/p&gt;

&lt;p&gt;Actual outcome: Redstone block turns invisible.&lt;/p&gt;

&lt;p&gt;Expected outcome: Redstone block stays visible.&lt;/p&gt;

&lt;p&gt;Bug also exists for other blocks if you power them&lt;/p&gt;

&lt;p&gt;Probably the same underlying issue as &lt;a href=&quot;https://bugs.mojang.com/browse/MC-177&quot; title=&quot;Clocked piston arm turns invisible when exiting game/dying/etc.&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MC-177&quot;&gt;&lt;del&gt;MC-177&lt;/del&gt;&lt;/a&gt;, but this particular issue can not be reproduced anymore because of changed piston behavior.&lt;/p&gt;</description>

                            <comment id="48811" author="jonathanhaas" created="Fri, 1 Mar 2013 21:56:55 +0100"  >&lt;p&gt;I filed &lt;a href=&quot;https://bugs.mojang.com/browse/MC-10677&quot; title=&quot;Pistons fire more than once per tick / block teleporting&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MC-10677&quot;&gt;&lt;del&gt;MC-10677&lt;/del&gt;&lt;/a&gt; for the new weird sticky piston behavior.&lt;/p&gt;</comment>
                            <comment id="47231" author="banana478" created="Sat, 23 Feb 2013 18:00:39 +0100"  >&lt;p&gt;Got it now. For me, there is both the redstone block and an invisible one that occupy the same space and experience z-fighting with each other. Upon destroying the redstone block, the invisible one continues around.&lt;/p&gt;</comment>
                            <comment id="47217" author="jonathanhaas" created="Sat, 23 Feb 2013 16:17:17 +0100"  >&lt;p&gt;Bug seems to be sort of resolved with sticky pistons but still happens on normal ones. &lt;/p&gt;

&lt;p&gt;If you build the 4-piston setup with sticky pistons it looks like the block is pushed through all 4 positions in one single tick, which is very weird. But at least it doesn&apos;t turn permanently invisible.&lt;/p&gt;

&lt;p&gt;Behavior for non-sticky piston seems to be unchanged.&lt;/p&gt;</comment>
                            <comment id="47206" author="grygrflzr" created="Sat, 23 Feb 2013 15:26:50 +0100"  >&lt;p&gt;Confirmed to still occur on 13w07a with the four piston setup if no repeater delays are added. Reopened.&lt;/p&gt;

&lt;p&gt;EDIT:&lt;br/&gt;
Actually, also occurs with 2-piston setup without repeaters after waiting a few seconds.&lt;/p&gt;</comment>
