Light created by lightning strikes does not disappear ever #782

Closed ghost closed 6 years ago

ghost commented 7 years ago

Empty plugins folder. Tested queued light updates true and false.

When lightning strikes it will lit up an area around it along with fire, once this fire fades the light caused by this is stuck in that area forever, and seems like no matter what you do the blocks stay lit up. This is server side and restarts do not make it disappear.

Cannot reproduce this on any of my servers, plugins or no.

This remembers me to the effect of using W.E.. Light source blocks that only dissapear when you place a block right on it. it mostly happens with blocks like glowstone/lava.

ghost commented 7 years ago

Is nobody able to reproduce?

It also appears that the lighting in the area is "legitimate" and mobs will not spawn in it. Breaking blocks around it or placing torches and removing them does not remove this ghost lighting.

ghost commented 7 years ago

Can you take a screenshot? What setup are you using? (the config settings etc.) And how do you spawn the lightning? I think there is not enough information to solve this problem.

ghost commented 7 years ago

Default generated configs on a default type world. Only thing I changed after experiencing this bug was changing queued light updates to true from false, which did not appear to fix or change anything.

The lightning happened naturally in vanilla gameplay.

Basically blobs of light with no source left all over the world after lightning happens naturally.

  1. Does the same bug also happen in vanilla, bukkit and or spigot?
  2. Can you make a step list for reproduction? (try the list for yourself to check if works!) Answering these 2 things will hopefully give more detail about the bug.

edit: misreading zetglobs post. removed dumb question. thanks @polkovnikov-ph

@dodohacker He have just told that the lightning happened naturally. At least make it seem as if you cared for comments.

unload and reload the chunk

zachbr commented 6 years ago

Paper has recently undone several lighting patches added by Spigot that essentially prevent the proper lighting routines from running.

Please let us know if you continue to see this behavior against the latest builds.
