| Description |

Note This issue is about sunlight. For the related block light issue, see The bugCertain blocks "save" sunlight, emiting it even after the original source has been removed. This creates an annoying glowing spot and is very difficult to clean up given that the blocks are not obviously the source of the glowing (and that it can chain between multiple of them). Affected blocks (may be incomplete)

No, it's a bug and the blog author was already notified. |

Redstone ore is supposed to do this, according to Minecraft.net here. However, this may be wrong, because I doubt the author would know definitively what the desired behavior should be here. |

Confirmed for 1.10, glowstone not affected. You can see the result with cobweb on this video : https://youtu.be/fZa-kKz-K3E What i think is that when the ceiling is sealed, all the air blocks's light level underneath are updated but they omit other blocks (for optimisation purpose) so cobweb is not updated except if you place the block just above it (for glass and other stuff it works though) F3 confirms that the light is skylight, not block light |

Please mark both videos (https://youtu.be/bPUdssOvU78 and http://youtu.be/8nTd1KbbrLA) as either public or hidden, if it's private, we can't watch them. |

Confirmed for 1.9-pre1, although glowstone doesn't seem to be affected anymore. It still occurs with water and cobwebs. |

Confirmed in 15w47c. It interferes with the operation of daylight sensors, which think the "saved" light from glowstone, etc. are daylight and emit a signal where there should be none. It's also difficult to fix once it occurs, because the "sky light" emitting from one block of glowstone will be "saved" as "sky light" in nearby blocks, so they must all be broken before you can replace them or else it'll still think there's skylight around. |

Bug still confirmed in 15w38b. It's been 3 years, maybe it's time to fix it, Mojang? |

this is still a problem in 1.7.10 and 14w28b |

I can also confirm for 14w21b. Additionally powered redstone blocks act as transparent and exhibit this behavior. It seems that transparent blocks often do not update their light level, thus preserving previous sky light levels. I've had this same problem with stained glass but am having trouble duplicating it. |

can confirm for 14w21b |

Is this still a concern in the latest Minecraft version 14w04b? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases. |
