The bug
When a block on fire is broken, the light of the destroyed fire is not updated.
How to reproduce
Put a tree on fire and wait for the destruction of the blocks and you will observe the not updating of the brightness level (also affects the menu F3
).
Note
From @unknown:
This is partially resolved in 18w44a (iirc already 18w43c).
Lighting is now correct clientside. However according to F3 it's still wrong serverside.
Relogging fixes the serverside part. However, at least for spawn chunks, teleporting away and returning won't fix the issue and the wrong lighting is then actually synced to the client.

Can you please check if that's still an issue in the most recent snapshot? I think this might be fixed now.

Might be related to MC-30939

Seems to be fixed in 18w46a.
However, MC-30939 still seems to exist.
Can anyone confirm this?

Is this still an issue in 19w14a?
