            <title>[MC-11630] Ender Crystals can grief even if gamerule mobGriefing is set to false.</title>
                <link>https://bugs.mojang.com/browse/MC-11630</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;Ender Crystals can grief stuff even if the gamerule mobGriefing is set to false, so that people can use 3rd party programs to spawn ender crystals, and they will destroy stuff.&lt;/p&gt;

&lt;p&gt;Steps to reproduce:&lt;br/&gt;
-Go to the end.&lt;br/&gt;
-Find an ender crystal.&lt;br/&gt;
-Build something so close to it/around it.&lt;br/&gt;
-Make sure the gamerule mobGriefing is set to false.&lt;br/&gt;
-When you&apos;re done, punch the ender crystal.&lt;br/&gt;
-You&apos;ll see it destroyed part of your building.&lt;/p&gt;</description>

1) /scoreboard players tag @e&lt;span class=&quot;error&quot;&gt;&amp;#91;type=ender_crystal&amp;#93;&lt;/span&gt; add bottom &lt;/p&gt;
{ShowBottom:1b}

&lt;p&gt;2) Optional, if you want the players to get the ender crystal item back:&lt;br/&gt;
           1) /scoreboard objectives add placeCrystal stat.useItem.minecraft.end_crystal&lt;br/&gt;
           2) /execute @e&lt;span class=&quot;error&quot;&gt;&amp;#91;type=ender_crystal,tag=!bottom&amp;#93;&lt;/span&gt; ~ ~ ~ detect ~ ~-1 ~ obsidian * give @a&lt;span class=&quot;error&quot;&gt;&amp;#91;score_placeCrystal_min=1&amp;#93;&lt;/span&gt; end_crystal&lt;br/&gt;
           3) /scoreboard players reset @a&lt;span class=&quot;error&quot;&gt;&amp;#91;score_placeCrystal_min=1&amp;#93;&lt;/span&gt; placeCrystal&lt;/p&gt;

&lt;p&gt;3) /execute @e&lt;span class=&quot;error&quot;&gt;&amp;#91;type=ender_crystal,tag=!bottom&amp;#93;&lt;/span&gt; ~ ~ ~ detect ~ ~-1 ~ obsidian * kill @e&lt;span class=&quot;error&quot;&gt;&amp;#91;type=ender_crystal,tag=!bottom,r=1&amp;#93;&lt;/span&gt;&lt;/p&gt;</comment>

Is there a place this can be found? Or is it just going to grief our server either way?&lt;/p&gt;</comment>

&lt;p&gt;Confirmed for 14w30c&lt;/p&gt;</comment>

                            <comment id="52194" author="firehunterx" created="Wed, 13 Mar 2013 12:57:11 +0100"  >&lt;p&gt;Ender Crystals have absolutely no AI, therefore they aren&apos;t mobs. They are still entities, but they cannot do anything without interaction.&lt;/p&gt;

&lt;p&gt;They will not &quot;Willingly&quot; explode unless you make them.&lt;/p&gt;</comment>
                            <comment id="52154" author="banana478" created="Wed, 13 Mar 2013 01:36:27 +0100"  >&lt;p&gt;Yeah, that&apos;s like saying TNT shouldn&apos;t make explosions in mobGriefing is turned off.&lt;/p&gt;</comment>
                            <comment id="52129" author="08juan80" created="Tue, 12 Mar 2013 21:29:33 +0100"  >&lt;p&gt;Well people can use 3rd party programs to spawn them, they are entities I know. Well, they interact with the Ender Dragon. If this is invalid, close it. TNT carts have to do block damage because they are TNT carts, they have TNT.&lt;/p&gt;</comment>
