@corey manlen.

Light block should have a behavior similar to air, especially in survivial mode.

I think it's reasonable so that one can modify its texture via modifying the texture of oak planks.

@Jim Gersetich, that datapack modifies all biomes in overworld to fit new height.

@dan hop, your datapack doesn't modify or create any biomes. That's why it works fine.

Agree with@Kai , I prefer mojang to spend several weeks on fixing it. We can wait for a more stable snapshot so that we can test it and feedback.

 Set the file latest.log to "Read only" to solve this problem perfectly 😃

happens to latest 21w15a snapshot with world gen datapack.  Severe lag and null biomes.

But it doesn't prevent the growth of fungus.

Note that it doesn't prevent the growth of fungus, see MC-222761.

So I don't think it's intended.

Mining an iron ore with Fortune III will drop 1~4 raw irons, so I think that it's not an issue.

If you use a spawn egg on a mob with same id, it will spawn a baby mob.

It works on zombies, villager zombies, sheep, cow, etc.

It's not strange that the spawn egg and bucket have different behaviors.

I think that it works as intended because sleeping on a bed let you skip to the next sunrise.

It happens with normal pistons also

It's a pain as most my cities have gates connected to daylight sensors so that they open and close each day cycle to keep mobs out, now that the gravity blocks break gonna need to find a work around till it's fixed

Honestly don't know. 

Haven't been running server for a while now.  Not being able to load older versions of the game I don't know if I could reproduce this.  I did manage to work around this by breaking bed in Win10 game then place bed again.  I don't remember which version I used to place the bed and have it work.

Not sure if my friend was ever able to get bed to work who always connected using android version.

After a recent update that stated this was resolved the skin still reset after closed and relaunch for my windows 10 install.  After uninstall and install the game the problem was fixed.  

I recommend completing a full backup/export of all your world saves before doing this.  I lost all my saves and cannot find the means to get them back.  Windows 10 does indeed delete the folders and all contents entirely when removing the app.  I don't know how other platforms manage the saves.  Use caution.

I read that you can navigate to the folder of your world save; right click; and select Restore Previous Versions.    This didn't work in my case. 

my experience with this not only deprived me of all my inventory I gathered from several hours exploring the end; the entire structure I had found and saved in was not where I found myself when I next logged in.  I was relocated to a two floor end city somewhere else in the end.. In all my exploring I never once found the building I was in when I loaded the game.

I found once again the mammoth end city I was in when I save and quit to title screen all the cobble I used as scaffolding still remained.
