Fires can leave ghost lighting behind

Attachment - lightingbug.png

World version 13w05b, and this is part of the aftermath of an enormous jungle fire. Many areas have spurious light sources.

I'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 "source" and it'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?

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'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'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'm stuck with them for the foreseeable future.

I haven't had any /new/ lighting glitches, but if there's a way to trigger bulk updates throughout a region and clear the old ones, that would be wonderful!

its a feature not a bug.

another one, by fireballs

Is this still a concern in the current Minecraft version 1.7.2 / Launcher version 1.3.4 ? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

F3+A reloads all the chunks.

Yes, I think F3+A is a reasonable workaround. Demanding more than that would be greedy. So, OK to close, I guess, thx.

As this is only a workaround it is really important to keep this open as it is a bug 😉
Maybe not one of the heavy ones but still a bug

Yes, it is indeed still a bug.

Observed in 14w34d. Blaze attacks lit netherrack in an area that was completely dark. After putting out the fire, the affected areas were still fully lit.

Still in 1.8.

Still in 1.8.1. It seems that even if I'm right next to the fire it leave light behind (previously it only happened if the chunk was unloaded AFAIK).

Confirmed for 1.8.2-pre1.

Is maybe duplicated by MC-74665

For 1.8, 1.8.1 & 1.8.2-pre confirmed. Also was added before.

Okay, I am with TheMogMiner in a TeamSpeak and I figured out how to reproduce.
1. Create a world with seed: -5514359264657335283 in creative
2. Teleport to -239 90 595, you will now be in a birch forest
3. Execute the following commands:
/spawnpoint
/gamerule keepInventory true
/gamerule randomTickSpeed 100
/gamerule doDaylightCycle false
/time set 18000
4. Get a flint and steel and set the forest on fire at many places, kind of like on this picture is shown http://imgur.com/1b47MUX
5. Fly out a few 100 blocks to be sure that the chunks unload.
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))
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.

By the way, you can use MCEdit to update the lighting in your world if you need a specific area fixed.

confirmed for 1.8.3.

Added the world with ghost lighting as attachment. If it is fixed this world should not show any light glitches anymore.

Fresh (not carried over from previous versions) phantom lighting from a surface lava pond in 1.8.7

Confirmed in 1.8.8 and in 15w47c. 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.

Could be related to MC-93132.

Can confirm in 1.9.

Can confirm in 1.9.2.

after 3 years no improvement ... please add a better light updating

Confirmed for 16w33a.

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'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.

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.

That bug is back underwater in Snapshot 18w15a (see screenshot 2018-04-12 13.28.12)

Can confirm for 1.13-pre7

Still in 1.13.2. I have part of a Jungle that spans hundreds of blocks riddled with this

I found that, for some reason, filling up the area with the Ghost Lighting with leaves and letting the leaves decay make the lighting go away. I have no idea why it works but it's a good way to remove it.

Sadly, you can only place decaying leaves with commands, so if you want to remove it on, say, a survival world, you're out of luck.

This glitch still hasn't been fixed and I have yet to know what causes it.

I'm still seeing this behavior in 1.16.2
