            <title>[MC-1466] Monsters Spawning In light levels of Eight on SMP.</title>
                <link>https://bugs.mojang.com/browse/MC-1466</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;I am building a tower on a man made island and for most of the time there are no mob spawns except for squids, Iron golems, and slimes (Theres a 2x2 chunk slime farm on the island).&lt;/p&gt;

&lt;p&gt;Ocassionally I will spot a creeper, a skeleton, a spider, or a zombie roaming around on the ground floor. I&apos;ve searched every spot for light levels of 7 and below and there are only light levels of 8 and above.&lt;/p&gt;</description>

                            <comment id="60172" author="puzzlemage" created="Sat, 13 Apr 2013 18:35:47 +0200"  >&lt;p&gt;Light levels at my head were all 9 or better.  At my feet it would be 8.  Also, this only started happening a couple days ago.  I&apos;ve never had this trouble before, and I use this design a lot.  Also, the zombie appeared in the room directly over the one I was in, I was definitely within 24 blocks. &lt;br/&gt;
(My report, &lt;a href=&quot;https://bugs.mojang.com/browse/MC-13468&quot; title=&quot;Zombies have spawned in a well lit building&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MC-13468&quot;&gt;&lt;del&gt;MC-13468&lt;/del&gt;&lt;/a&gt;, was duped to this one.  See it for my specifics.)&lt;/p&gt;</comment>
                            <comment id="31466" author="bljat" created="Sat, 29 Dec 2012 23:58:39 +0100"  >&lt;p&gt;Ok first of all Endermen have the ability to teleport from anywhere to anywhere they like, happend one teleported right infront of you. Secondly this game has very simple mechanics whether a mob can spawn or not: if it&apos;s dark, mobs spawn - if it&apos;s light, mobs do not spawn. Also the game provides the simplest and cheapest way of preventing mobs from spawning: Torches! But if you insists of putting as little torches down as possible it is up to you to make sure every single block a mob can spawn is lit enough. As I tested sufficiently enough light levels above 7 prevent mobs from spawning.&lt;/p&gt;</comment>

That area where the zombie appeared, few step from there I saw a skeleton and had to kill it. So I went to check out where the heck it came from. While I was standing there A Enderman simply apeared by my side. There is any explanation for that? Always exists one explanation.&lt;br/&gt;
I am myself a programer and I know how dificult is sometimes to reproduce a bug. I ask you to reconsider this. And I have a guess: maybe there is some kind of spawn point that force mob to appear but that is not used anymore in-game.&lt;/p&gt;

&lt;p&gt;Its related to the &lt;a href=&quot;https://bugs.mojang.com/browse/MC-5530&quot; title=&quot;Mob spawn inconsistence&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MC-5530&quot;&gt;&lt;del&gt;MC-5530&lt;/del&gt;&lt;/a&gt;.&lt;/p&gt;</comment>

&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;went up high so ground below doesn&apos;t affect the mob spawning&lt;/li&gt;
	&lt;li&gt;build a platform with a glowstone roof so that all blocks on the platform had a light level of 8 - no spawns&lt;/li&gt;
	&lt;li&gt;raised the roof by 1 block - alsmost instant mob spawns&lt;/li&gt;
&lt;/ul&gt;

Though, mobs were never able to spawn like this in the past(in my experience) with a level 7 light on the ground and a level 8 above that.&lt;/p&gt;</comment>
