            <title>[MC-8167] Weird pulse behaviour.</title>
                <link>https://bugs.mojang.com/browse/MC-8167</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;A serial data transfer gone wrong. See this to understand the mechanism (at least the recepter) : &lt;a href=&quot;http://www.youtube.com/watch?v=gqryvkOpOJ0&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://www.youtube.com/watch?v=gqryvkOpOJ0&lt;/a&gt; (properinglish19)&lt;/p&gt;

&lt;p&gt;&lt;b&gt;What I expected to happen was...:&lt;/b&gt;&lt;br/&gt;
A inverted one tick pulse &quot;unBUDs&quot; a piston, updated by a comparator. Said piston retracts, depowering the redstone piece below the attached redstone block. The torch on the redstone piece&apos;s block then activates after a tick, powering the block above back to it&apos;s source wich in turn deactivate the torch one tick after, and before it can repeat the redstone block is pushed back in place. &lt;br/&gt;
There&apos;s a serie of these, one tick apart.&lt;/p&gt;

&lt;p&gt;The data line then feeds into the recepters as shown in the video above (only the timings and emeters are different).&lt;/p&gt;

&lt;p&gt;&lt;b&gt;What actually happened was...:&lt;/b&gt;&lt;br/&gt;
When placing the first 6 redstone blocks (the upper ones to prevent a pulse and write a 0) from right to left as shown in screenshots, the fifth bit is made a 1 in place of a 0. Place a redstone block in 6th bit and the 5th is a 0 again.&lt;/p&gt;

&lt;p&gt;&lt;b&gt;Steps to reproduce:&lt;/b&gt;&lt;br/&gt;
Screenshots should hopefully be enough to reproduce it. Don&apos;t mess up the timing, it&apos;s important.&lt;/p&gt;</description>

If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.&lt;/p&gt;</comment>
