            <title>[MC-1809] Some trees generate with leaves too far from logs</title>
                <link>https://bugs.mojang.com/browse/MC-1809</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;Some trees generate with leaves too far away from logs causing them to decay once they are updated by placing and removing a log block.&lt;/p&gt;

&lt;h3&gt;&lt;a name=&quot;Affectedtrees&quot;&gt;&lt;/a&gt;Affected trees&lt;/h3&gt;
&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;large (2 &#215; 2) jungle&lt;/li&gt;
	&lt;li&gt;acacia&lt;/li&gt;
	&lt;li&gt;dark oak&lt;/li&gt;
&lt;/ul&gt;


&lt;h3&gt;&lt;a name=&quot;Howtoreproduce&quot;&gt;&lt;/a&gt;How to reproduce&lt;/h3&gt;
&lt;ol&gt;
	&lt;li&gt;Generate one of the trees listed above&lt;/li&gt;
	&lt;li&gt;Set a heigh &lt;tt&gt;randomTickSpeed&lt;/tt&gt; gamerule value
&lt;div class=&quot;code panel&quot; style=&quot;border-width: 1px;&quot;&gt;&lt;div class=&quot;codeContent panelContent&quot;&gt;
&lt;pre class=&quot;code-java&quot;&gt;/gamerule randomTickSpeed 300
&lt;/pre&gt;
&lt;/div&gt;&lt;/div&gt;&lt;/li&gt;
	&lt;li&gt;Place a log block next to the leaves and remove it again&lt;br/&gt;
&#8594; Some of the leaves decay&lt;/li&gt;
&lt;/ol&gt;

                            <comment id="330519" author="lukeonia1" created="Tue, 20 Sep 2016 21:04:20 +0200"  >&lt;p&gt;I looked more into Fabian&apos;s comment above... I guess the problem is &quot;fixed&quot; in that these leaves don&apos;t spontaneously decay on world generation, if that&apos;s what the original bug report is describing. But the root problem remains, and the leaves will still decay if they receive a leaf-related update.&lt;/p&gt;

&lt;p&gt;I&apos;m not entirely sure what &quot;check_decay&quot; is supposed to do? I&apos;m seeing leaves decay with &quot;check_decay&quot; set to False, so it seems to have no effect on whether or not a particular block decays on receiving a block tick.&lt;/p&gt;</comment>
                            <comment id="330411" author="lukeonia1" created="Tue, 20 Sep 2016 08:51:29 +0200"  >&lt;p&gt;Assuming this is referring to the same effect, can confirm for 1.10.2. Steps to reproduce:&lt;/p&gt;

&lt;p&gt;1) Generate a jungle giant tree, either naturally or from saplings and bonemeal.&lt;br/&gt;
2) Place a wood block at the edge of the canopy leaves.&lt;br/&gt;
3) Remove the wood block.&lt;br/&gt;
4) Wait a few minutes.&lt;/p&gt;

&lt;p&gt;The canopy leaves will rapidly decay from the original round shape to a smaller diamond-shaped configuration. I&apos;ve attached before-and-after pictures of a naturally-generated tree to which I&apos;ve done the above steps.&lt;/p&gt;

&lt;p&gt;EDIT: Fire (such as from lightning) will do the same thing, as will manually breaking a leaf block. Other types of block updates don&apos;t seem to have any effect, as Fabian pointed out above.&lt;/p&gt;

&lt;p&gt;It appears to be due to the decay rules for leaf blocks. They decay if they aren&apos;t connected within 4 blocks of a wood block, but jungle giants naturally generate with canopies larger than that. Hence, they remain in a sort of natural BUD state until they receive a suitable block update that triggers them to decay. Large oak trees are also be subject to this effect, but it&apos;s less noticeable due to their irregular shape.&lt;/p&gt;

&lt;p&gt;A simple workaround could be to modify jungle giants to generate with wood block &quot;branches&quot; embedded in their canopies. Otherwise, I don&apos;t know... Have separate decay rules for jungle leaves?&lt;/p&gt;</comment>
                            <comment id="321085" author="farogaming" created="Sat, 16 Jul 2016 18:38:30 +0200"  >&lt;p&gt;Test with large jungle trees: Leaves have the meta data part &quot;check_decay&quot; (+8) that is only true when the block touches a log block or a block next to it receives a block update. Then it checks if it should decay. From my tests just a block update does nothing, so it apparently only checks for decay if the block update was a leave decaying or a log being removed. That means that it&apos;s fixed for 1.10.2. Correct?&lt;/p&gt;</comment>

Specifically, it&apos;s jungle leaves on the top edges of the really tall trees.&lt;/p&gt;</comment>

                            <comment id="51412" author="bugi74" created="Sat, 9 Mar 2013 20:58:53 +0100"  >&lt;p&gt;Sean: Uh, not exaggerating at all there? At least for me, the leaves that will decay will do it soon enough, and the amount of leaves lost is insignificant. I merely consider it a free source of saplings and an occasional apple.&lt;/p&gt;

&lt;p&gt;Say, move to the area, start building temporary work base (platform, walls, roof, some chest, work stuff, unload crap from inventory). Leave Steve (safely) idling there for a cup of coffee/tea/healthy walk around the block. Come back, no more leaves decaying, so start working. Still more than 90% of original leaves left, way too much for my liking.&lt;/p&gt;

&lt;p&gt;Not saying there is no related bug(s), but it certainly does not make jungles unplayable.&lt;/p&gt;

&lt;p&gt;If, somehow, the jungle is getting almost completely stripped from leaves, there is some other problem going on, and very very likely not part of vanilla code.&lt;/p&gt;</comment>

At first I thought it was a feature until I read it under the bugs section on the minecraft wiki.. I kind of like it actually. Shouldn&apos;t trees dropp saplings and apples naturally anyway? That&apos;s my opinion at least.&lt;/p&gt;</comment>
