            <title>[MCPE-17464] Extended pistons retract for a second when the world is loaded.</title>
                <link>https://bugs.mojang.com/browse/MCPE-17464</link>
                <project id="10200" key="MCPE">Minecraft (Bedrock codebase)</project>
                    <description>&lt;p&gt;From &lt;a href=&quot;https://bugs.mojang.com/browse/MCPE-19086&quot; title=&quot;Pistons forget their extended state on world reload&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MCPE-19086&quot;&gt;&lt;del&gt;MCPE-19086&lt;/del&gt;&lt;/a&gt;:&lt;br/&gt;
The extended state of pistons is not saved in the file, instead their state is recovered on the chunk load by ticking them with some delay.&lt;br/&gt;
&lt;span class=&quot;image-wrap&quot; style=&quot;&quot;&gt;&lt;a id=&quot;130439_thumb&quot; href=&quot;https://bugs.mojang.com/secure/attachment/130439/130439_forgetful-pistons.jpg&quot; title=&quot;forgetful-pistons.jpg&quot; file-preview-type=&quot;image&quot; file-preview-id=&quot;130439&quot; file-preview-title=&quot;forgetful-pistons.jpg&quot;&gt;&lt;img src=&quot;https://bugs.mojang.com/secure/thumbnail/130439/_thumb_130439.png&quot; style=&quot;border: 0px solid black&quot; role=&quot;presentation&quot;/&gt;&lt;/a&gt;&lt;/span&gt;&lt;br/&gt;
In the screenshot shown above, the sticky piston is permanently powered and thus should never retract. But if you reload the world the piston momentarily retracts and triggers the dispenser containing a water bucket.&lt;/p&gt;

&lt;p&gt;Original description:&lt;br/&gt;
When loading the world extended pistons that aren&apos;t in the same chunks has the player will retract for a second. It seems to effect 3 to 4 chunks away from the player.&lt;/p&gt;</description>

Previously I&apos;d have the pistons retract maybe once in every 10 world loads. Now, it happens every single time. &lt;/p&gt;</comment>

                            <comment id="348014" author="zebulanstanphill@gmail.com" created="Fri, 9 Dec 2016 17:03:18 +0100"  >&lt;p&gt;Reopening... I have found out that this is in fact a separate issue from &lt;a href=&quot;https://bugs.mojang.com/browse/MCPE-13608&quot; title=&quot;Redstone components update when world is reloaded&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MCPE-13608&quot;&gt;&lt;del&gt;MCPE-13608&lt;/del&gt;&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;Attached screenshot &amp;amp; test world from &lt;a href=&quot;https://bugs.mojang.com/browse/MCPE-19086&quot; title=&quot;Pistons forget their extended state on world reload&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MCPE-19086&quot;&gt;&lt;del&gt;MCPE-19086&lt;/del&gt;&lt;/a&gt;.&lt;/p&gt;</comment>
                            <comment id="338272" author="zebulanstanphill@gmail.com" created="Thu, 27 Oct 2016 16:50:02 +0200"  >&lt;p&gt;&lt;del&gt;After further testing, I have concluded that this bug is the same as &lt;a href=&quot;https://bugs.mojang.com/browse/MCPE-17464&quot; title=&quot;Extended pistons retract for a second when the world is loaded.&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MCPE-17464&quot;&gt;&lt;del&gt;MCPE-17464&lt;/del&gt;&lt;/a&gt;, where redstone components update upon world-reload. Some contraptions with pistons may update during world load and cause pistons to be momentarily unpowered, resulting in this problem. Closing this ticket as a duplicate.&lt;/del&gt;&lt;/p&gt;</comment>
                            <comment id="336325" author="zebulanstanphill@gmail.com" created="Fri, 21 Oct 2016 19:08:12 +0200"  >&lt;p&gt;Confirmed to occur in 0.16.0. (Tested on Windows 10.) I was loading my redstone testing world and could hear some pistons retract as the world loaded. It happens every time I load the world. Not sure if it happens to all pistons or not. Will need to do more testing...&lt;/p&gt;</comment>
                            <comment id="335453" author="zebulanstanphill@gmail.com" created="Sun, 16 Oct 2016 22:08:30 +0200"  >&lt;p&gt;Could you provide screenshots of the pistons that you have seen retract upon world load? It&apos;s hard to tell what is going on if we don&apos;t know what is powering the pistons. A world download would also be helpful.&lt;/p&gt;</comment>
