I created a survival world in 21w06a and there's a lot (I already found 6) of dark areas in the overworld, even in the day there are zombies and skeletons spawning in these areas without burning.
I searched and didn't find a report of this bug in this snapshot.

Yep, I'm getting that too.Β
I just downloaded 21W06A, and found a bug. I also have several screen shots of it. There are these narrow areas but are very long. The run in a north & south directions and are dark but look like scorched earth but theyβre not. Mobs do spawn in them, during the day you can see the sun, but everything is dark on the surface. I mean really dark, darker than night. During the day you canβt sleep in them, until night time. The light levels vary a lot, as low as 2. I have several screen shots. with and without torches.Β Β
