In version 20w21a I was using a "datapack" to generate a dungeon system for a minigame.
When updating the world to 20w22a, I found that on certain occasions the generated structures have an incorrect lighting between "Server and Client".
(The map can be downloaded and to activate the generation, there is a command block with a lever on it.)

This also happens when just using
/fill
, just like in MC-172980.Here's a video showcasing the issue:
