            <title>[MC-7349] TNT Minecart &quot;Ticking Entity&quot; Crash</title>
                <link>https://bugs.mojang.com/browse/MC-7349</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;&lt;font color=&quot;red&quot;&gt;&lt;b&gt;&lt;em&gt;This is NOT a duplicate of &lt;a href=&quot;https://bugs.mojang.com/browse/MC-7324&quot; title=&quot;Nuke Effect form TNT Minecarts&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MC-7324&quot;&gt;&lt;del&gt;MC-7324&lt;/del&gt;&lt;/a&gt;, which had a different stack trace to my bug, although it had the same name. It is also not a duplicate of &lt;a href=&quot;https://bugs.mojang.com/browse/MC-6804&quot; title=&quot;minecart tnt bug&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MC-6804&quot;&gt;&lt;del&gt;MC-6804&lt;/del&gt;&lt;/a&gt; as this bug is incomplete, whereas mine contains a full crash report.&lt;/em&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p&gt;When multiple TNT minecarts collide (I used 5), the game lags up, they make the rail sound continuously and explode with stronger than usual force. The game then crashes with a &quot;Ticking Entity&quot; bug.&lt;/p&gt;

&lt;p&gt;&lt;b&gt;What I expected to happen was...:&lt;/b&gt;&lt;br/&gt;
The minecarts produce the equivalent of 5 TNT explosions upon colliding, or do nothing.&lt;/p&gt;

&lt;p&gt;&lt;b&gt;What actually happened was...:&lt;/b&gt;&lt;br/&gt;
The minecarts stopped, and my game lagged up. I got the &quot;dirt screen of death&quot; which then oddly disappeared and returned to the game. I heard explosions and saw items flying away but the terrain did not update for a few seconds, then I saw a &lt;b&gt;huge square TNT crater pattern&lt;/b&gt; (characteristic of the old Tekkit Nukes (&lt;b&gt;THIS WAS NOT TEKKIT OBVIOUSLY&lt;/b&gt;)). The game then &lt;b&gt;crashed&lt;/b&gt;. Earlier, it did not crash but lagged so badly (0fps, not responding) that I had to force quit.&lt;/p&gt;

&lt;p&gt;&lt;b&gt;Steps to Reproduce:&lt;/b&gt;&lt;br/&gt;
1. Create some sort of long, booster powered railway that ends in a wall.&lt;br/&gt;
2. Place multiple TNT carts at the end and fire them all at the wall.&lt;br/&gt;
3. They will stop at the end and lag the game before exploding and then crashing the game.&lt;/p&gt;
