            <title>[MC-2642] Renamed items won&apos;t stack when thrown on the ground (may cause lag)</title>
                <link>https://bugs.mojang.com/browse/MC-2642</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;&lt;b&gt;Short Summary&lt;/b&gt;&lt;/p&gt;

&lt;p&gt;I was building a redstone mechanism using a tutorial from the Youtuber &quot;Sethbling&quot; called &quot;Smart Item Payment Machine in Minecraft&quot; for my adventure map. I wanted to create a system, where I toss in a renamed item into a hole, where the items stack so they don&apos;t move along and activate a signal to prevent a a door to open for example.&lt;/p&gt;

&lt;p&gt;So items that are renamed won&apos;t stack on the ground, making it possible for griefers to lag a server by spamming the items on the ground. It also won&apos;t let my system work, because i only want specific, renamed items to work with the machine.&lt;/p&gt;

&lt;p&gt;&lt;b&gt;Steps to Reproduce:&lt;/b&gt;&lt;br/&gt;
1. Rename any item at an anvil (it has to be a stack of 64 at once!)&lt;br/&gt;
2. Throw them on a ground&lt;br/&gt;
3. They don&apos;t stack like normal items do to prevent lag and item spam on multiplayer servers.&lt;/p&gt;</description>

I haven&apos;t tried yet for the version 1.4.4 but I don&apos;t think that they&apos;ve solved the problem yet.&lt;br/&gt;
Try another block like bricks or something and rename them to derp and throw them on the ground.&lt;br/&gt;
They shouldn&apos;t stack right now&lt;/p&gt;</comment>
                            <comment id="20084" author="jonathanhaas" created="Fri, 9 Nov 2012 22:45:19 +0100"  >&lt;p&gt;Works for me in 1.4.4. I renamed a whole stack of cactus blocks in creative mode at once (using different methods like shift-clicking or just taking them out) and throwning them on the ground makes them stack.&lt;/p&gt;

&lt;p&gt;Obviously items with different names are not supposed to stack and they don&apos;t do.&lt;/p&gt;

&lt;p&gt;Please provide better steps to reproduce.&lt;/p&gt;</comment>
