            <title>[MC-10343] Leaving world when riding stacked entities unstacks or deletes the stack</title>
                <link>https://bugs.mojang.com/browse/MC-10343</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;A player on a pig in a minecart who relogs will cause the minecart to disappear.  &lt;br/&gt;
See &lt;a href=&quot;http://www.youtube.com/watch?feature=player_detailpage&amp;amp;v=wuZnVmcBY1o#t=218s&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;this video by sethbling&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;Alternatively, see &lt;a href=&quot;http://youtu.be/W4FIqYIh3UM&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;this video&lt;/a&gt; to see what it looks like from another player&apos;s perspective.  &lt;/p&gt;

&lt;p&gt;&lt;ins&gt;&lt;b&gt;Steps to reproduce:&lt;/b&gt;&lt;/ins&gt;&lt;br/&gt;
&lt;b&gt;1.&lt;/b&gt; Run this command to create the needed entities: &lt;/p&gt;
&lt;div class=&quot;preformatted panel&quot; style=&quot;border-width: 1px;&quot;&gt;&lt;div class=&quot;preformattedContent panelContent&quot;&gt;
&lt;pre&gt;/summon Pig ~ ~5 ~ {Saddle:1,Riding:{id:Pig,Riding:{id:Pig}}}&lt;/pre&gt;
&lt;/div&gt;&lt;/div&gt;
&lt;p&gt;&lt;b&gt;2.&lt;/b&gt; Mount uppermost entity&lt;br/&gt;
&lt;b&gt;3.&lt;/b&gt; Disconnect/Unload world&lt;br/&gt;
&lt;b&gt;4.&lt;/b&gt; Join/Load world&lt;/p&gt;

&lt;p&gt;&lt;ins&gt;&lt;b&gt;Result:&lt;/b&gt;&lt;/ins&gt;&lt;br/&gt;
&lt;em&gt;&lt;b&gt;Local game:&lt;/b&gt;&lt;/em&gt; Deletes all but the uppermost entity of the stack&lt;br/&gt;
&lt;em&gt;&lt;b&gt;External Server:&lt;/b&gt;&lt;/em&gt; Decouples the uppermost entity from the stack; all other entities remain stacked correctly.&lt;/p&gt;</description>

It unstacks upon disconnect &amp;#8211; &lt;em&gt;the topmost pig is actually disconnected with the player&lt;/em&gt;.  I think I see what the cause of this is &amp;#8211; it should disconnect the entire stack, not only the topmost pig.&lt;/p&gt;</comment>

While tricky to test for a local world (you could examine the NBT data, but it can be a pain to find the right chunk), it shouldn&apos;t be too hard to test on a server with someone else there to observe.&lt;/p&gt;</comment>

I logged off of my account night before last riding a horse and when I logged on the next day the horse was gone, and the saddle that was on it. I closed out of the game without saving to see if it would be the same and it was, the horse and saddle were gone.&lt;/p&gt;</comment>

&lt;p&gt;&lt;ins&gt;&lt;b&gt;Title:&lt;/b&gt;&lt;/ins&gt;&lt;br/&gt;
Disconnecting/unloading world when riding stacked entities decouples and/or deletes stack&lt;/p&gt;

&lt;p&gt;&lt;ins&gt;&lt;b&gt;Steps to reproduce:&lt;/b&gt;&lt;/ins&gt;&lt;br/&gt;
&lt;b&gt;1.&lt;/b&gt; Run command (13w37a and above only, or create stack with external tool): &lt;/p&gt;
&lt;div class=&quot;preformatted panel&quot; style=&quot;border-width: 1px;&quot;&gt;&lt;div class=&quot;preformattedContent panelContent&quot;&gt;
&lt;pre&gt;/summon Pig ~ ~5 ~ {Saddle:1,Riding:{id:Pig,Riding:{id:Pig}}}&lt;/pre&gt;
&lt;/div&gt;&lt;/div&gt;
&lt;p&gt;&lt;b&gt;2.&lt;/b&gt; Ride uppermost entity&lt;br/&gt;
&lt;b&gt;3.&lt;/b&gt; Disconnect/Unload world&lt;br/&gt;
&lt;b&gt;4.&lt;/b&gt; Join/Load world&lt;/p&gt;

&lt;p&gt;&lt;ins&gt;&lt;b&gt;Result:&lt;/b&gt;&lt;/ins&gt;&lt;br/&gt;
&lt;em&gt;&lt;b&gt;Internal Server:&lt;/b&gt;&lt;/em&gt; Deletes all but uppermost entity of the stack&lt;br/&gt;
&lt;em&gt;&lt;b&gt;External Server:&lt;/b&gt;&lt;/em&gt; Decouples uppermost entity from the stack, all other entities remain stacked correctly.&lt;/p&gt;

&lt;p&gt;&lt;ins&gt;&lt;b&gt;Addition versions this bug affects:&lt;/b&gt;&lt;/ins&gt;&lt;br/&gt;
1.6.3, 13w36a, 13w36b, 13w37a, 13w37b&lt;/p&gt;</comment>
                            <comment id="47909" author="carmeops" created="Wed, 27 Feb 2013 08:19:04 +0100"  >&lt;p&gt;as i understand it (probably need more testing) here is how it work:&lt;/p&gt;

&lt;p&gt;when you disconnect when riding an entity, the entity is disconnected and stored with you&lt;/p&gt;

&lt;p&gt;if the entity (like the pig) is riding other entities (like the cart) it disconnect all the stacked entities but only store with you what you are directly riding&lt;/p&gt;

&lt;p&gt;so if sethbling tested disconnecting on his mob tower with a boat on top, he would reappear with only the boat&lt;/p&gt;


&lt;p&gt;also: someone should try a mod allowing to ride other players and disconnect on top of someone to see what it does&lt;/p&gt;</comment>
