Random light sources in the world

Summary:
Light sources can sometimes appear in the world. They appear randomly all over the world (in all dimensions). Reloading changes the location/removes the light sources.

Steps to reproduce:

  1. Import the world (20 MB) https://drive.google.com/file/d/1vqUcfpiopRLQ91Z_qCTZtqB-1-cd2Nwf/view?usp=share_link

  2. Set the render distance to 10 chunks.

  3. Open the world.

  4. Go around the completely cherry biome you spawned in (until you find the light).
    If not found, reload the world.

  5. Reload the world near the found light.

Observed results:
Light sources randomly appear in the world.

Expected results:
Light sources will not appear randomly in the world.

Notes:
In the provided world, the problem only seems to happen in the cherry biome (and in some previously loaded places like spawn), but in my Realms (1.19.71) it happens everywhere in huge numbers. Realms weighs about 1 GB and the light appears very randomly, so I do not attach it here. If it is also needed, I can attach it. Also, all players of the Realms see the light (synchronously).

I wonder if there might be a light emitting block near Y = 0 where this light appears?

[Mod] EVGENSYPERPRO

No, this has nothing to do with the Y = 0 coordinate. But it feels like the light is duplicated in some cases.

Issue appears on my Bedrock Server running on Linux. BDS Version is 1.19.73.02.

Having the same issue on our server, Verified by myself and other members.  The lines tend to be in a straight line when appearing. One member said the lines were under her mob farm and completely stopped all mobs from spawning. Which makes me think that its not a visual glitch, but that game actually thinks those area's are lit up.  Verified on BDS multiplayer 1.19.73 server. 

Edit- Verified there are no light blocks present in any of the Y value along the "light".

Also verified there are no light blocks present around 0 x Y x 0.

First screen shot is directly below the lights position.

The second is directly above the lights position.

The bug still appears on version 1.19.80.02 Bedrock Linux Server.

Having this issue on a realm as well. I have observed monsters spawning inside the random lights, I’ve tried placing torches near the lights and removing them to update the lighting but nothing changed. The owner of the realm said he did not see the lights whem asked and I thought the only difference was that he was the only one who had not been in the nether that night, but still observed random lights after restarting and looking without entering the nether. All of us are on Xbox. The lights observed are in areas of various generation versions.

I have this exact issue and it's very annoying.  When I save and close and reopen the lights disappear, but then they show up again as I move further along the terrain.

This is an odd one:  I have the issue on Minecraft for Windows and with my PS4 and PS5, however oddly, I've not encountered it on my Switch as yet.

Got the same issue on my realm, is getting really annoying and is apparent all over my world. Block updates do not cause the issue to cease, and it is also appearing frequently underwater. I have checked for light sources yet there is none present. I am on v1.19.81 and this is still an issue. Other players have reported that they also see this bug, so it would not be client side. Removing and applying texture packs does not alter the issue. Currently this seems to be a problem across all platforms.

Screenshots from my realm below:

5.22.2023...my world tonight has the same light patterns in it...just updating the dates with my post....the same as up top.

migrated

I’m having the same issue on my survival multiplayer realm. When in download the world from my realm and load it in singleplayer the issues are gone but when i re-upload the world the same issues appear again. I get lines of light all over my world. Mostly in chunks i loaded previously. New chunks look like they’re fine. The light lines generate right on, or next to every other chunkborder in the world.

I can confirm the issue is still occurring as of update 1.20 on bedrock Ps5, and Windows

I started seeing this in the final build of 1.19 (1.19.83) and it has carried over to 1.20

XeroTheCaptain

As of the latest update on bedrock realms, im still having this issue. Long lines of lights, clumps of scattered lights, lights on maps i only just discovered, etc.

Affects 1.20.10.23

This is also on my realm. The entire world is covered in these lines for thousands of blocks in each direction. It makes it so when it's night, it feels like day but with a night sky. It's really annoying. I have not seen it in any worlds yet, just my realm.

migrated

I have this issue on my Realm as well. 

The highest light level is on chunk borders (coords divisible by 16) and it happens both above and below ground. It happens below Y-0. I haven't been able to confirm if the same light level is constant in a X,Z coordinate. 

Save The Bedrock

because it says: platform = Windows... The same Bug exists on the Playstation

I have had this issue for months, and they still haven't patched it. If it helps, my world was created in 2019 before the caves and cliffs update. Perhaps this bug affects older worlds?

migrated

It is harder to notice, but I believe it is also happening in the Nether. I noticed some portions of a bridge I was building were inexplicably brighter. The bridge was over a lava sea, but only small areas were affected.

Affects 1.20.0

It's happening too on my realm world, in great swaths all the way across the world. Check my attachment for screenshot (super annoying!!)

Do these light sources affect mob spawning, one spawned in my creeper farm and I don't know if it is ruining the rates

Asdra

These light sources do not affect mob spawning, I have watched hostile mobs spawn inside them on multiple occasions, so they are purely visual

migrated

Thank you I spent hours on the farm and didn't want it to ruin it. This makes the issue a lot less of a problem to me thanks

migrated

I think it's cause of light block of the moon lights.

It doesn’t appear to be present when you view it from the mobile version of the game.

This bug persists and has gotten worse with the 1.20.30 update.

Save The Bedrock

It concerns version 1.20.50 on my realm

noisynatobot

Lighting bugs still occur quite often on my world, although they are not lines, but regions of bright areas in closed rooms.
