            <title>[MC-177] Clocked piston arm turns invisible when exiting game/dying/etc.</title>
                <link>https://bugs.mojang.com/browse/MC-177</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;To reproduce in singleplayer:&lt;/p&gt;

&lt;p&gt;Build the attached design (first screenshot, or third screenshot for a design that doesn&apos;t depend on BUDs), flip the lever on. Note: The piston is a sticky one. The piston should extend and retract quickly.&lt;/p&gt;

&lt;p&gt;To cause the bug, either&lt;/p&gt;
&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;die&lt;/li&gt;
	&lt;li&gt;alt-tab out of minecraft for some time&lt;/li&gt;
	&lt;li&gt;save, exit to menu and reload the save&lt;/li&gt;
	&lt;li&gt;just wait, walk/or look around as it seems to happen randomly, too&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;Actual outcome:&lt;/p&gt;
&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;The piston is still pulsing, but the piston arm and the pushed block is invisible (picture 2)&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;Expected outcome:&lt;/p&gt;
&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;Piston arm still visible&lt;/li&gt;
&lt;/ul&gt;

Dying or reloading the game seems to reproduce the issue in a reliable way.&lt;/p&gt;</comment>
