I wasn&apos;t clear enough with my comment. I meant that I don&apos;t know if this issue as a whole is working as intended, and I still don&apos;t. &lt;img class=&quot;emoticon&quot; src=&quot;https://bugs.mojang.com/images/icons/emoticons/smile.png&quot; height=&quot;16&quot; width=&quot;16&quot; align=&quot;absmiddle&quot; alt=&quot;&quot; border=&quot;0&quot;/&gt;&lt;/p&gt;</comment>

&lt;p&gt;The TNTs are now visually inside the blocks in 15w46a. I don&apos;t know if that&apos;s intended or not.&lt;/p&gt;</comment>
                            <comment id="218234" author="trazlander" created="Fri, 6 Feb 2015 06:02:14 +0100"  >&lt;blockquote&gt;&lt;p&gt; Actually, this bug&apos;s description/title is wrong. The real bug is that tnt entity is actually in the dirt block but displayed above 1 block on client-side. &lt;/p&gt;&lt;/blockquote&gt;

&lt;p&gt;Ya this is true. A TNT entity that is within a dirt block is of course going to blow up that dirt block, and be able to chain the explosion to other explode-able blocks around it. A TNT entity is not an item entity, so it&apos;s not going to get pushed to the side or anything, it&apos;s just going to sit inside that block until it explodes. The bug here is the visual TNT is getting displayed on top of the block instead of just visually staying inside of it.&lt;/p&gt;

&lt;p&gt;This is what it looks like in-game: &lt;a href=&quot;http://i.imgur.com/7aGyIry.png&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://i.imgur.com/7aGyIry.png&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;But quickly logging out and opening MCEdit, you can see the TNT entity (red box) is sitting on top of the dispenser, within the obsidian block: &lt;a href=&quot;http://i.imgur.com/i5OdLVP.png&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://i.imgur.com/i5OdLVP.png&lt;/a&gt;&lt;/p&gt;</comment>

The real bug is that tnt entity is actually in the dirt block but displayed above 1 block on client-side. Confirm this by running following command before TNT blows up : &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;/execute @e[type=PrimedTnt,r=5,c=1] ~ ~ ~ summon Chicken ~ ~ ~ {Invulnerable:1,NoAI:1}&lt;/pre&gt;

&lt;p&gt;This bug is still present in snapshot 14w19a.&lt;/p&gt;</comment>
                            <comment id="154198" author="zeel" created="Thu, 1 May 2014 01:09:04 +0200"  >&lt;p&gt;Still a problem in 14w18a&lt;/p&gt;

&lt;p&gt;Problem is present in various scenarios where TNT is submerged in water. The effect is unreliable, but common.&lt;/p&gt;

&lt;p&gt;Water is supposed to keep TNT from destroying blocks, however it is failing to do so. This renders numerous (almost all) cannon designs useless.&lt;/p&gt;

&lt;p&gt;This issue needs updated as the problem occurs in a much broader range of situations than the original issue suggests. Many of the &quot;duplicate&quot; issues are more inclusive (and better written), and should be looked into.&lt;/p&gt;</comment>
                            <comment id="149575" author="simnico" created="Tue, 1 Apr 2014 17:52:29 +0200"  >&lt;p&gt;Confirmed in 14w11b. &lt;br/&gt;
My TNT cannon randomly blows up when I use it with 6 TNT blocks (ignited with redstone during the same tick). Sometimes everything works fine, but sometimes the TNT just ignores the flowing water.&lt;br/&gt;
It did not happen with 1 or 2 TNT as far as I can tell. &lt;br/&gt;
I did not test 4 or 5.&lt;br/&gt;
EDIT : Further testing showed that the bug occurs with 3 TNT (11 explosions/30 tries), but is at least unlikely with 1 or 2 TNT (0/30 for both).&lt;/p&gt;

&lt;p&gt;Fortunately I was in creative when I found this bug, I can&apos;t imagine my reaction if it destroyed half of a redstone device in survival...&lt;br/&gt;
Please fix this bug :&apos;(&lt;/p&gt;</comment>
                            <comment id="143528" author="xlash123" created="Fri, 28 Feb 2014 01:49:37 +0100"  >&lt;p&gt;I can duplicate this bug every time I make a TNT cannon. It seems to have to do with having enough fire power. For example, 1 block of TNT will not break any blocks underwater, but 5 will break blocks underwater.&lt;/p&gt;</comment>
                            <comment id="143499" author="zedaph" created="Thu, 27 Feb 2014 20:08:31 +0100"  >&lt;p&gt;As Victor said, it is a wider range of circumstances where this happens. Please update this to be slightly more generalized as TNT in water sometimes (most of the time for me) blows up blocks around it, not just when dispensed from an upwards dispenser with a block on top.&lt;/p&gt;

&lt;p&gt;Lots of things that have been marked here as duplicates, where in actual fact this should have been marked under one of them as this only explains &quot;part&quot; of the bug.&lt;/p&gt;</comment>

                            <comment id="51756" author="lucas.werkmeister" created="Mon, 11 Mar 2013 11:38:50 +0100"  >&lt;p&gt;Confirmed in Release Candidate.&lt;br/&gt;
This also happens when the dispenser is facing sideways, but &lt;b&gt;not&lt;/b&gt; when it&apos;s facing downwards. Also, the block in front is necessary.&lt;/p&gt;</comment>
