Its Just A Lighting Glitch! It Should Be Fixed In Later Version I Think?

Yea is strange since don't see a strong light source. Similar to that I've seen the flip side where there are eerie dark spots that occur what seems to be randomly in some worlds. I will try to add a picture showing it. Place was originally a dark cavern and I added torches to light up and that spot stayed dark. I wonder was your place light at first and then you boxed yourself in?

Still am not sure of all the logistics of how this is triggered esp in the original poster's case, but in my case it seems to be tied in with torch use. (idk about that dark space version) I have seen the light a few times in places where I had a torch to help grass grow and took the torch away. It seems the space has the memory of where the light was. It reverts to normal appearance when I place a new torch and take it away.

First one looks like it could be a normal shadow, hard to tell.

What the heck is up with the second picture? It looks like a snow-topped block except it's sand-topped... Sand-topped sand. No idea what to make of that.

With the third picture, could those cobblestones on the right actually be backwards-facing stone stairs? Those would let light through.

Yea, idk what to make of the first one either. I hadn't seen it replicated yet but thought it a curiosity. Usually see a gradual shading and not abrupt.

The second is sand, grass, and water. Showing what I wonder may be a replication of the light glitch the original poster added, but can't verify. I noticed it while walking and when placed/removed a torch at the spot it returned to normal.

Am not sure what to make of the last picture though unless OP is able to go into more detail how found that spot and what blocks are affected.

I posted a new grouping showing the same thing as the other trio. In my case it does seem to be the system somehow holding memory of where torches were. Placed torches to give dirt extra light to grow and then took torch away when grass was made. While playing it looked normal, but when reloaded next day noticed it in some places again. It has been appearing randomly where I had a torch in the past. Not all torch locations have this occur though. This and another one forgot to picture were from torches I removed during the daytime. I Wonder if try again but remove torches only at night will not occur. Doesn't bother me or affect game play; just find it curious.

@Michelle, thanks, for some reason I just wasn't seeing the water in that second picture.

From what you're describing, it sounds to me like the blocklight data stored in chunks.dat is not always being updated when it should.

I wonder if this could be related to MCPE-115 – torch gets destroyed without doing the normal torch-destroying routine, blocklight doesn't get updated?

Michelle 2012-09-24T05:23:02Z

I took the initiative to destroy the torches in these cases so don't think it is directly related to that report. It does seem more that it's not completely registering/updating that I took away the torch so that makes sense. Sometimes programs can be quirky in what triggers a bug so guess can't rule out if the two issues are related somehow. I made it a habit to remove any torches before breaking blocks since I noticed that bug also.

OOC: Going to be busy these next days so I may not reply again until Oct 2.

On the image of the house, I have had the same problem. Torchlight sometimes cuts off randomly long before it should in my mines.

Troy Parry 2012-10-10T13:44:11Z

I get the same problem as the picture at the start of certain seeds. After placing a torch in the area, it removes the problem.
As what John Doe says, I have the same problem. Removing the torch and placing it again will correct the lighting.

Troy Parry 2012-10-23T11:11:30Z

Well i've confirmed that this problem isn't limited to the start of a seed. I just had the problem happen to me after I deleted dirt, then reload the game. I had a "0 light" block where the dirt used to be, and it was daytime.

Richard Vargas 2012-10-23T20:44:08Z

I always have that problem. It's a bug that should be fixed. Also, why do your hearts intersect your control pad?

mike 2013-03-11T11:12:33Z

I get it a lot for 6.1 . If you have a map with overhangs, they get it a lot.

Chen 2013-03-11T13:50:16Z

Try out this bug I found: 1. Place a torch. 2. Go to home screen. 3. load back world. 4. there is a line of darkness beside the torch

mike 2013-04-03T11:21:57Z

Confirmed for 0.6.1

sbd01 2013-04-05T01:19:49Z

This is a very popular bug and has most likely been there since day one. It still exists on the PC version as well. To fix it, you usually have to place or delete a block inside of the glitched area.

This still happens in 0.7.0, 0.7.1, and 0.7.3.

Do 2013-07-23T07:48:22Z

Good catch, thanks.

Luis Robles 2013-09-10T03:16:26Z

Still happening as of version 0.7.5

Jackietheboy d 2013-11-04T16:42:32Z

And 0.7.6

Luis Robles 2014-01-12T23:28:40Z

Still happening in 0.8.1

Lafoog 2014-08-04T18:06:29Z

Does this issue still affect the current version of Minecraft PE? If so, please update the "Affected Version/s" option to reflect this.
