[Experimental] Tile entity data and entities gone after update from 1.17.30.22 to 1.17.30.23

Its the same for me. ( 1.17.30.23 - xbox series x )Every chest is now empty, all villagers disapeard, animals dead, signs with items are now empty, all beds changed colour and so on. 

I suppose it will be gone untill next update. 

But only if you / we are lucky the kopie of the world (if you have one) and not yet opened in this version, it can still be like before. 

Allways make a copy of the map in every case there is an new update Before opening the map! 

Clearly when i opened copies of the map the bug appeard. 

In 5 different copies the map was in different MB / sises after saving. 

Everyone of them are allso smaller in saved space than the "original map". 

/// This issue are now solved for me anyhow. And Iwe got a coupple of saves from 1.17.30.22 so i didnt "loose" anything but playing time! Everything with chest, villagers and so on are like it was before.

However there seems to be a moved problem. Now in 1.17.30.24 its chaos if i try and get into nether! But that is in an other report in here. Search for it ///

The game says that I am at like y=110 even though I am right above the sea (which, under normal circumstances, is at y=64), just to confirm your suspicion, Gruntastic. Also, I get the feeling that this bug and another one where new worlds cannot load chunks below y=0 are related to each other.

This issue was reported in an earlier beta and analyzed at MCPE-124552, but it’s not clear how/why it happened then. What is clear is that block data has shifted by +64 Y while the coordinates stored in entity and tile entity data remain unchanged. The result is massive death and data loss. See the mentioned report for a full listing of effects.

All chests empty, item frames empty, villagers dead. Can someone from Mojang please respond with an answer to the question - Will we get our items and villagers back?

Reply from @unknown: It is not possible for Mojang to restore your lost data. Your save data is stored locally on your device. No log or backup exists (unless you made your own backup, in which case only you would have access).

Every beta version and experimental feature is potentially unstable and Mojang always advises about the risk and making backups.

Thanks for the answer [Mod] GoldenHelmet ! 

That means that iwe got it right about to make a map copy everytime i start to play, a specially just when a new update are released. 

I make at least 3 every time,. One org, one to test and so on. 

That means that if i got it right ill wait with my map that never opened in 1.17.30.23 but are a save from 1.17.30.22 when all was "correct" and ill test it in 1.17.30.24 (when this bug are supposed to be solved) ill go on where i stopped / saved in 1.17.30.22 

So,. It will be shown by then but i think im right!❓  

Am i?

All of the mob heads that I placed down turned in to skeleton heads

Was teleported to cave below workplace, unsure why. Enderchest seems to be intact, but otherwise, no items in regular chests, or barrels

Any idea if a backup could be opened in a future version without this bug?

If you have a backup that was created before this update and hasn't been opened during this update, then simply do not open the backup until the bug is fixed. Changes and bugs only affect worlds that have been opened while the they are still in effect. Once the bug is removed, it will be safe to open it without the bug occurring.

My xbox one wont let me copy a world save since it is over 2gb... i spent years on this map... since xbox 360 years... also i went in the nether but all those chests are fine... the only other issue is that when i returned to the over-world i was loaded into bedrock itself

I noticed this fatal bug when all my chests were divided and y-axis was heightened to an abnormal condition so that clouds are close to the sea level, not to mention the husbandry loss. In addition, all the contents in chests are gone. Duplicating doesn't help for me. I'm wondering whether the "Save and Quit" process corrupted the record.

I was playing a beta world, survival (not experimental), after a while I turned on experimental features (caves and cliffs) probably 2 weeks ago.

When I saved on the prior version, I was in a house on the surface (66 +/-).

I saved, quit, ran the update. Rebooted the Xbox and loaded back into the world.

I was at height 64, bit in a deep underground cave.

I dug up and at height 115, I found the stronghold that I knew was in the area.

All chests were empty! The rest of it seemed fine. I continued to the surface and found my house and village. 

All Chests were empty (they were full beforehand), and all villagers were gone. 

The sea level was at 128, and the clouds were all at ground level.

I will investigate after the next update but assume the world is broken and all progress since he last copy/save are gone forever...

My world is ruined all my chests are empty and all the villagers are gone. Another problem only 2 villagers spawn in a big village and they don't breed.

Same thing, world height changed, (certain areas dropped by like 60 idk) all cows and pigs dead, weirdly, cats and iron golem were alive. All chests empty. All beds changed to red

Krisha Jain: your experience sounds like chunk data shifted -64, not +64 like this report describes. Cats and iron golems would survive that because they don’t take fall damage. We are getting reports of that happening in 1.17.30.24, such as MCPE-140428. Please confirm which beta version your issue happened in and find or create a new report for it.
