            <title>[MCPE-396] Duplication Glitch when mining and quitting immediately</title>
                <link>https://bugs.mojang.com/browse/MCPE-396</link>
                <project id="10200" key="MCPE">Minecraft (Bedrock codebase)</project>
                    <description>&lt;p&gt;Duplication Glitch&lt;/p&gt;

&lt;p&gt;You should get one item.&lt;/p&gt;

&lt;p&gt;Instead you get two items.&lt;/p&gt;

&lt;p&gt;1. Mine item&lt;br/&gt;
2. While still holding down from mining, immediately hit pause and then quit to title&lt;br/&gt;
3. Go back into world&lt;br/&gt;
4. The item will be in your inventory and back on the spot where you chopped it down already.&lt;/p&gt;</description>

&lt;p&gt;&lt;b&gt;Scenario: Expected: picking up an item, quitting and loading - the item should be in my inventory, there should not be a duplicate on the ground&lt;/b&gt;&lt;br/&gt;
Given there is an item on the ground&lt;br/&gt;
When I pick up the item&lt;br/&gt;
And force quit Minecraft pocket&lt;br/&gt;
And open the world again&lt;br/&gt;
Then the item is in my inventory&lt;br/&gt;
And the item is &lt;b&gt;NOT&lt;/b&gt; on the ground&lt;/p&gt;

&lt;h1&gt;&lt;a name=&quot;Whatactuallyhappenedwas...%3A&quot;&gt;&lt;/a&gt;What actually happened was...:&lt;/h1&gt;
&lt;p&gt;*Scenario: Actual: picking up an item, quitting and loading - There item is duplicated - it&apos;s in my inventory and on the ground&lt;br/&gt;
Given there is an item on the ground&lt;br/&gt;
When I pick up the item&lt;br/&gt;
And force quit Minecraft pocket&lt;br/&gt;
And open the world again&lt;br/&gt;
Then the item is in my inventory&lt;br/&gt;
And the item is an item on the ground&lt;br/&gt;
When I pick up the item&lt;br/&gt;
Then I have the item twice in my inventory&lt;/p&gt;


&lt;h1&gt;&lt;a name=&quot;StepstoReproduce&quot;&gt;&lt;/a&gt;Steps to Reproduce&lt;/h1&gt;
&lt;ol&gt;
	&lt;li&gt;Put one item in your inventory (step 1.png)&lt;/li&gt;
	&lt;li&gt;Throw it on the ground (step 2.png)&lt;/li&gt;
	&lt;li&gt;Wait for 10 seconds (presumably the inventory and the map chunks both save at this time)&lt;/li&gt;
	&lt;li&gt;Pick up the item&lt;/li&gt;
	&lt;li&gt;Immediately quit (presumably the inventory is saved immediately, but we are quitting before the map chunks have saved, as per comments by &lt;a href=&quot;https://bugs.mojang.com/secure/ViewProfile.jspa?name=luisrobles&quot; class=&quot;user-hover&quot; rel=&quot;luisrobles&quot;&gt;luisrobles&lt;/a&gt;)&lt;/li&gt;
	&lt;li&gt;reload the world (step 3.png)&lt;/li&gt;
	&lt;li&gt;You can see you have the item in the inventory and on the ground (step 4.png)&lt;/li&gt;
	&lt;li&gt;Picking up the item proves it&apos;s duplicated, as it&apos;s in the inventory twice (step 5.png)&lt;/li&gt;
&lt;/ol&gt;


&lt;p&gt;Doesn&apos;t follow the ACID test: &lt;a href=&quot;http://en.wikipedia.org/wiki/ACID&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://en.wikipedia.org/wiki/ACID&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;&lt;b&gt;System info&lt;/b&gt;&lt;/p&gt;
&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;I am using an iPhone 6+&lt;/li&gt;
	&lt;li&gt;I am using MCPE 0.10&lt;/li&gt;
	&lt;li&gt;I am in survival mode&lt;/li&gt;
&lt;/ul&gt;

I noticed this when MCPE locked up and I force closed it. I had been trying to pick up a crafting bench, and didn&apos;t think anything of it when I reentered my world after restarting MCPE, I just picked up the crafting bench that was there. I went to place what I thought was my only crafting bench at the time and found I had 2.&lt;/p&gt;

&lt;p&gt;I think this may also be the issue that put me on top of a tree I thought I had chopped down, again after a lock up and force close cycle. The tree (and a couple of others I know I chopped down) were present again.&lt;/p&gt;</comment>
