            <title>[MC-9188] Fires can leave ghost lighting behind</title>
                <link>https://bugs.mojang.com/browse/MC-9188</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;The problem of ghost lights remaining after the fire has gone is well-known for /lightning/, but I have seen it for other fires too. I had a big fire in a jungle and now that area is riddled with phantom light sources. This fire burned for many game days and I generally stayed out of the area until it had practically all burned out because of horrendous lag it caused, but it obviously gave many, many chances for this bug to manifest.&lt;/p&gt;

&lt;p&gt;Caveat: While the fire finally finished burning its last few blocks in release 13w05b, the sites of the phantom lighting that still remain may be from while I was running earlier releases. Possibly months earlier, because I have no idea how long it&apos;s been since I last visited this part of the world.&lt;/p&gt;

&lt;p&gt;(If you have an old world like mine, are there any established ways to force it to update a large area to catch glitches like these, or is the game engine supposed to do it automatically?)&lt;/p&gt;</description>

I have no idea why it works but it&apos;s a good way to remove it.&lt;/p&gt;

&lt;p&gt;Sadly, you can only place decaying leaves with commands, so if you want to remove it on, say, a survival world, you&apos;re out of luck.&lt;/p&gt;

&lt;p&gt;This glitch still hasn&apos;t been fixed and I have yet to know what causes it.&lt;/p&gt;</comment>

                            <comment id="353375" author="nogluten" created="Tue, 10 Jan 2017 01:43:18 +0100"  >&lt;p&gt;I am still getting the bug in 1.11.2. I lit a forest on fire to remove it, then left to work on other things nearby, when I returned there are random areas of light still throughout the area. I tried F3+A like mentioned here, however that doesn&apos;t make the lighting glitches go away, placing blocks where the light sources are appears to work, however there is no way to actually know where the light is coming from which makes this option extremely tedious, and not really feasible. The world is in realms making it rather difficult for me to use MCEdit. There is also a second area in the world where this happened, however that area was created back in 1.8 or so, but I doubt that it has much to do with that.&lt;/p&gt;

&lt;p&gt;Edit: I figured out a way to fix the lighting issues, however you can only do it when you are an op. Basically you make a large body of water (ie ocean) and clone it to about y100-200 depending on the forest you burned down. Then let the water fall and all ghost lights should be gone. Then just clone open air back to where you cloned the water and you should be good to go after the water has gone.&lt;/p&gt;</comment>

To reproduce, I left the area of the fire so the chunks unload, then returned to wait for the fire to burn out.  However (at least in 15w47c) if you then leave the area with the ghost light so the chunks unload, then return, the ghost light is gone.&lt;/p&gt;</comment>

                            <comment id="216819" author="karstvgl" created="Fri, 23 Jan 2015 22:52:52 +0100"  >&lt;p&gt;Okay, I am with TheMogMiner in a TeamSpeak and I figured out how to reproduce.&lt;br/&gt;
1. Create a world with seed: -5514359264657335283 in creative&lt;br/&gt;
2. Teleport to -239 90 595, you will now be in a birch forest&lt;br/&gt;
3. Execute the following commands:&lt;br/&gt;
/spawnpoint&lt;br/&gt;
/gamerule keepInventory true&lt;br/&gt;
/gamerule randomTickSpeed 100&lt;br/&gt;
/gamerule doDaylightCycle false&lt;br/&gt;
/time set 18000&lt;br/&gt;
4. Get a flint and steel and set the forest on fire at many places, kind of like on this picture is shown &lt;a href=&quot;http://imgur.com/1b47MUX&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://imgur.com/1b47MUX&lt;/a&gt;&lt;br/&gt;
5. Fly out a few 100 blocks to be sure that the chunks unload.&lt;br/&gt;
6. Stay here a minuit orso to be sure that the fire is gone (how higher the randomTickSpeed how faster you can get back. But how more lag and how more likely the bug to fail. (Sounds strange))&lt;br/&gt;
7. Teleport back to -239 90 595 if it is right the trees are burned down and a ghost lighting is still there. Which will still be there also a world download will be available on the dropbox down below.&lt;br/&gt;

                            <comment id="45072" author="simons mith" created="Sun, 10 Feb 2013 21:31:29 +0100"  >&lt;p&gt;I can sometimes clear individual glitches by forcing a block update nearby. But most of them originate from points in space where leaf blocks used to be, so there&apos;s no visual hint as to their precise location, making building over them a real chore. And given the sheer number of glitches, clearing them all up would be thoroughly impractical. I&apos;m hoping there is (or will be) some way of prodding the game engine to clear up at least a chunk at a time, otherwise I&apos;m stuck with them for the foreseeable future.&lt;/p&gt;</comment>
                            <comment id="43891" author="darkfigure" created="Wed, 6 Feb 2013 00:33:36 +0100"  >&lt;p&gt;I&apos;ve seen this kind of bug before but with lava, and before this snapshot. The only way I fixed it was put a block over the &quot;source&quot; and it&apos;d go away, but the moment the block I placed is removed, it is back. Try placing dirt around the area(s) and see if that helps, that is the only solution I can think of, or maybe try restarting your game or reloading the world? &lt;/p&gt;</comment>
