            <title>[MC-3703] Redstone changing orientation doesn&apos;t update previously powered blocks correctly</title>
                <link>https://bugs.mojang.com/browse/MC-3703</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;h3&gt;&lt;a name=&quot;Thebug&quot;&gt;&lt;/a&gt;The bug&lt;/h3&gt;
&lt;p&gt;When a line of redstone dust updates and does not / points at a block, the block is not updated under certain circumstances. (redstone redirection)&lt;/p&gt;

&lt;h3&gt;&lt;a name=&quot;Affectedsituations&quot;&gt;&lt;/a&gt;Affected situations&lt;/h3&gt;
&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;Block connecting to redstone dust is placed. This includes all blocks that connect to redstone dust (like repeaters, levers...) without creating a redstone signal, see &lt;span class=&quot;nobr&quot;&gt;&lt;a href=&quot;https://bugs.mojang.com/secure/attachment/14077/14077_Redstone+bug.png&quot; title=&quot;Redstone bug.png attached to MC-3703&quot;&gt;Redstone bug.png&lt;sup&gt;&lt;img class=&quot;rendericon&quot; src=&quot;https://bugs.mojang.com/images/icons/link_attachment_7.gif&quot; height=&quot;7&quot; width=&quot;7&quot; align=&quot;absmiddle&quot; alt=&quot;&quot; border=&quot;0&quot;/&gt;&lt;/sup&gt;&lt;/a&gt;&lt;/span&gt;&lt;/li&gt;
	&lt;li&gt;Redstone dust which was blocked before connects, see &lt;span class=&quot;nobr&quot;&gt;&lt;a href=&quot;https://bugs.mojang.com/secure/attachment/22834/22834_2013-03-01_01.21.12.png&quot; title=&quot;2013-03-01_01.21.12.png attached to MC-3703&quot;&gt;2013-03-01_01.21.12.png&lt;sup&gt;&lt;img class=&quot;rendericon&quot; src=&quot;https://bugs.mojang.com/images/icons/link_attachment_7.gif&quot; height=&quot;7&quot; width=&quot;7&quot; align=&quot;absmiddle&quot; alt=&quot;&quot; border=&quot;0&quot;/&gt;&lt;/sup&gt;&lt;/a&gt;&lt;/span&gt;&lt;/li&gt;
	&lt;li&gt;Redstone dust connecting downwards from glowstone (see &lt;span class=&quot;nobr&quot;&gt;&lt;a href=&quot;https://bugs.mojang.com/secure/attachment/154719/154719_2017-10-04_14.14.30.png&quot; title=&quot;2017-10-04_14.14.30.png attached to MC-3703&quot;&gt;2017-10-04_14.14.30.png&lt;sup&gt;&lt;img class=&quot;rendericon&quot; src=&quot;https://bugs.mojang.com/images/icons/link_attachment_7.gif&quot; height=&quot;7&quot; width=&quot;7&quot; align=&quot;absmiddle&quot; alt=&quot;&quot; border=&quot;0&quot;/&gt;&lt;/sup&gt;&lt;/a&gt;&lt;/span&gt;), slabs, hoppers, redstone blocks (see also &lt;a href=&quot;https://bugs.mojang.com/browse/MC-123850&quot; title=&quot;Redstone dust doesn&amp;#39;t update shape of connecting redstone dust when going up onto transparent blocks&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MC-123850&quot;&gt;&lt;del&gt;MC-123850&lt;/del&gt;&lt;/a&gt;)&lt;/li&gt;

                            <comment id="427016" author="theosib2" created="Thu, 4 Jan 2018 18:24:17 +0100"  >&lt;p&gt;It seems that technical users find this behavior to be extremely useful, while pretty much nobody finds it to be harmful.  BUDs weren&apos;t initially intended, but it&apos;s one of those &quot;emergent behaviors&quot; that even Mojang developers have acknowledged it as being generally productive and desirable, even if some less experienced uses may initially find it to be unintuitive.  Intuitive behavior is always a good objective, but we can see how trying to make redstone more intuitive has basically made it broken and useless in Bedrock edition, while at the same time introducing even uglier bugs and even more nondeterminism.  &lt;/p&gt;

&lt;p&gt;If you want to see an example of productive use of this feature, check out this video:  &lt;a href=&quot;https://www.youtube.com/watch?v=vMYygzMYUs4&amp;amp;feature=youtu.be&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://www.youtube.com/watch?v=vMYygzMYUs4&amp;amp;feature=youtu.be&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;I suggest marking this but as &quot;works as intended&quot; or &quot;won&apos;t fix,&quot; because of all the frustration &quot;fixing&quot; it would cause.&lt;/p&gt;

&lt;p&gt;Any further discussion, we can move to /r/mojira or the EigenCraft discord.&lt;/p&gt;

&lt;p&gt;Thanks.&lt;/p&gt;</comment>

                            <comment id="48534" author="kuubaku" created="Fri, 1 Mar 2013 02:04:57 +0100"  >&lt;p&gt;Hmmm. This looks too stable and consistent to be a BUD... at first glance. &lt;br/&gt;
I toggle the switch - torch goes off - piston retracts - redstone orientation changes - torch magically stays depowered. Then I toggle the switch again - torch magically regains power - piston extends - redstone reorientates to correct state. I get this 100% of the time, but when left alone for some time in this magic state, torch updates itself and piston performs a cycle. Such a funny device...&lt;/p&gt;

&lt;p&gt;The pistonless setup on the first screenshot works as expected to me though.&lt;/p&gt;</comment>

Observe how the torch is off eventhough no wire is connected. (the randomness comes from the fact that the torch receives updates randomly)&lt;/p&gt;</comment>
