From what it seems, Allays that were generated/spawned pre-1.19.1 aren't able to duplicate. However, any newly generated/spawned allays seem to be able to duplicate just fine. I'm having this same issue in another world where the allays I have were generated before 1.19.1.

If possible, could you give the seed to the world? It needs to be reproducible to be a bug.

You appear to be using "shaders".

Turn them off and see if the problem persists.

I wonder how soon can you fix this bug and let me download my 700mb world?

ｉface the same problem，how can ｉget my world back?

Same here. Game crashes even with chunk and particle render ranges turned down almost to minimum.

For those that may have the issue: It's resolved by manually installing your intel driver's to be a lower version that's been approved by acer, it can be found on their website for your perspective model.

I'm having the exact same issue. This happens also with vanilla 1.14

UPDATE: After downloading 1.10 I tried the nether portal achievement and got nothing. Went back to casually playing and found a ship wreck. Explored it a bit then finally went inside for the treasure map, the Ahoy achievement popped. This got me excited so I went back to try the nether portal achievement again and it didn't unlock. Will try a few other easy ones that didn't work yesterday and report back when I can.

SECOND UPDATE: Achievement working again, got a few, including a previously known glitched achievement(Super Fuel).

@Diane - I think you are correct.  Did not think to search for "skylight".

Same issue with my mob grinder in 19w11b snapshot world.  Added snip of screen from a room totally enclosed by oak planks and cobble.  Light levels say 15.  Should be zero.  Only possible source of light is a half-slab opening 20m below at the bottom of the mob drop pit.  When sun rises, mobs at bottom of pit (non-fatal fall for XP grinding) start to burn and die.  Should be light level zero down there too despite half-slab opening.

I cannot unlock these 2 achievements (Renewable Energy and Super Fuel) on the Kindle Fire edition either. I've tried multiple times on multiple worlds.

Mash-up packs are looking good in the 1.5.1 update. Cheers.

One question, though: are the DLC purchased from legacy Switch edition, when upgraded to Bedrock on Switch, supposed to be available to us on other platforms, like Windows 10? Looked at the Minecraft store from my PC, and I don't have the packs on there.

I have the same problem. I bought the Halo, Egyptian, Greek, Norse, Roman, Skyrim and Fallout Mash-up packs on the old Switch Edition. They carried over to the new Bedrock version and linked to my Microsoft account. All of these packs, when loaded from the game options, produce error textures (the pink/black checkers) and other incorrect textures on the menus. The map that comes with each pack doesn't load, and trying to create a new world with the mash-ups' texture pack crashes the game. Basically, the same results as shown in the original post. The only part of the mash-up packs that I can access are the skins. Only two mash-up packs work properly: the Christmas-themed Festive Mash-up Pack, and the Switch-exclusive Super Mario Mash-up Pack. I am on the latest update.

I'm hoping this issue gets attention. I expect the DLC I purchased to work through the entire lifetime of the game, not become obsolete in a new version of the game without warning.

Same it's making me stay on the title screen are u serious I spent $10! For this to happen!

Same thing happened to me I watched every video I could! And I did everything Google play store said! But Still it does it!

This just happened to me. Riding a horse, then save and reload to view the terrain faster and the horse was gone.
