MCPE-60566Top of light emitting blocks will occasionally fail to emit any light
From time to time, light emitting blocks will fail to have their top side lit. Oddly, this glitch did not affect the beacon. I have so far failed to repeat the glitch, but the majority of blocks were placed during the day, and any subsequent blocks placed that emitted light, excluding the beacon, were also glitched. However, it only seemed to affect a certain patch of land, so it might have to do with the chunks they were in.

First, let's see if we can finally get some attention to this bug. It seems to have started with 1.13 and was even reported (though not in a clear way) for beta versions. I think this report has the best description, comments, and votes, so that's why I'm commenting here.
List of duplicates:
On light not updating across chunk borders: MCPE-61247, MCPE-61096, MCPE-60586, MCPE-60635, MCPE-59480, MCPE-56847, MCPE-56795, MCPE-56297, MCPE-54462, MCPE-50902, MCPE-49882
On light not updating across sub-chunk (vertical borders): MCPE-60566, MCPE-55697
Second, has it occured to anyone else that this bug might be the cause of, or at least a major contributor to, MCPE-49616 (Mobs spawning in lit areas)? That report and some of its duplicates also specifically say the problem started with 1.13, and some say that the "lit" areas where mobs spawned looked dark (e.g. MCPE-55614).
Maybe this is related to
MCPE-49616.I used some torches to lit up my guardian farm and one time I visited there all the blocks above the torches in one corner of the farm were dark and mobs were spawning next to a torches but just one block higher. I planted new torches at the dark places and removed them right away and the light levels were fixed, but I think I experienced this same bug.
It seems that when you reload a chunk the lighting does not update properly from one chunk to another or between subchuncks (16-block vertical sections) within chunks. See comments on
