World corrupted / deleted after a power cut or game crash

it happens when it auto saves when the power goes out
a solution would be to have the world save to 2 different places, at different times, so only one can be corrupted at a time.

I noticed that there was a change to how autosave works in 1.14.1. Everything in the world save database is normally supposed to be reachable by starting at a MANIFEST-xxxxx file. When the world is changed, the changes are written to new files and the older versions of those files are left unchanged so that in the event of corruption, the older version of the world can be recovered. The MANIFEST file is likewise left unchanged so that you can use it to find those older files.

During gameplay, autosave creates the new versions and maintains an in-memory copy of the MANIFEST, which it updates to point to the new version files. However, it doesn't write the in-memory copy to the MANIFEST file, because then you'd lose the ability to recover. Instead, it saves the in-memory copy to a file called CURRENT, and only copies CURRENT to MANIFEST after all the updated files are in sync.

Prior to 1.14.1, third-party tools could leverage this scheme by accessing the database through the MANIFEST file, even when the world was open and being played. This enabled them to see a slightly outdated version of the world, since MANIFEST isn't kept strictly up to date by the game. (Technically, this technique is forbidden, but as long as you don't allow the third-party tool to update anything it won't cause any damage to the database.)

Since 1.14.1, however, I find this technique no longer works. If you use a third-party tool to open the MANIFEST file while the world is being played, what the tool sees is a completely empty world, not a slightly outdated one. It's as if the information in the MANIFEST file is now being erased when the world is opened. The game and autosave generally seem to work fine (except perhaps in the event of a power failure recovery) so I have to assume the changed behavior was intentional. But it demonstrates that they did change something about how the world save and autosave work, so it's possible they introduced a bug that prevents recovery from succeeding under some abnormal circumstances.

@Justerfrog yes I do this now sometimes, but it's lame and boring, I have to copy the world every now and then to name sure my world is safe. 

@Auldrick so this means there's something wrong with the new system, right? I really hope this gets attention because it's an important problem and it's causing good worlds getting corrupted every day. Please fix the recovery process asap.

We can't say for sure at this point that what I observed in 1.14.1 is a bug, because it's something that doesn't affect gameplay and there's no authoritative definition of how it's meant to work. What I saw might have been an intentional change to the world save and is working as it's intended to, and it's just a coincidence that whatever is causing your world corruption sounds like it could be related.

We have tagged the developers asking whether they think what I saw might be a bug and might be causing your problem (as well as another bug we've found that sounds like it could be related). If they agree, we'll forward this report to them through the normal channels. But even if they say it's not related, there's still some kind of issue here and we'll pursue it. It'll just be harder to narrow down on it in that case, and we'll probably have to get more information from you. So stay tuned.

I +Hope Its ok by 2nd Febuary 2020+

@unknown: It sounds like you might be having a similar problem. It's always helpful to have additional experiences and points of view on a bug ticket, especially during its early days. Can I ask you to add your experience? (Please mention what platform you're playing on as well.)

Well, it isn't just me. I saw an other post on Reddit claiming the same issue, even with screenshots.

I noticed there's a new update (1.14.2), I'll try and see if it's fixed on this new version. Can anyone do me a favour and try this out? Just put a new world on your PS4, wait until the game saves a few times then unplug their console without exiting the game file, and see if it corrupts or not

If you have a copy of the world available, you might like to upload a copy of it for investigation.

• On Windows 10 you can use the Export world feature.

• On Android or iOS you need to use a file explorer to navigate to Device storage > games > com.mojang > minecraftWorlds

• On Xbox or Switch the only way is to upload it to a Realm, and then download the world on Windows 10 or Android/iOS. (Please do not purchase a Realms subscription just to provide a world to us - but if you have a Realm already this may be a viable option if you wish to do so.)

Here are the steps to retrieve a copy of the world save from PS4:

Make sure your BLANK USB stick has been formatted to FAT32
Go to Settings > Application Saved Data Management > Saved Data in System Storage > Copy to USB Storage Device > Select Minecraft > Select Saved World to copy > Copy
You can then upload and share that world copy. If the world is larger than 10MB you can upload the world to OneDrive or a similar file sharing site, and then share the link.

I will try to corrupt a world and upload it here tomorrow, but there's a new 1.14.2 update. Maybe it's fixed, I'll try to see if a world would corrupt in a powercut anymore

Update : Yes, worlds still corrupt after power cuts, just made a test world and played for a while then unplugged my PS4 on purpose, the world got corrupted. I'll try and upload it for you.

Another Update : You can't copy corrupted files to a USB drive, meaning the corrupt world is stuck in my PS4 forever unless I delete it or the bug fixes, please help I'm not seeing any serious effort in fixing it this has been an issue since Minecraft PS4 switched to Bedrock, and has been reported too many times. Please do something

Any updates guys? 

My little sister's world which had hours of progress just went in a split second because of a power cut. I'm really disappointed, I pointed this one out 3 months ago and it's a game breaking glitch and it has been "passed over to the devs". How isn't this fixed? Please hurry up on this one

All I can tell you is that this report has been forwarded to the devs.

We would pass along any status information if we got it, but the bug tracker doesn't normally get status updates until the work is done. We're just a tool for reporting bugs, not a communication channel between you and the devs. The Community Managers are responsible for that when it's necessary.

Same thing happened to me. I would have started from a backup I made a couple days ago but somehow the moment I loaded that world it immediately corrupted. There goes five years down the drain.

Same happened to me. I shut down my computer when it froze on me, and my Minecraft world was gone from the list. I had tried to import (by using the .zip file rename trick), and I tried to copy the world to a different folder, but it was no use. Well, at least I found the world file in my folder...

This happened to multiple worlds of friends I know on PS4. We had a neighborhood powerout a couple days ago, and two of my friends had their worlds corrupted, one of which I was playing on.

Disable auto saving would solve 99.9 percent problems. I would rather lose progress from minutes to hours than having file permanently corrupted, etc

Try it on Console Edition with auto saving disabled. Not only it reduces problem, the performance is so great. This is a dream for Bedrock.

Still not fixed after latest update. 😞 Hopefully it can be fixed eventually and we can all get our worlds back!

I'm having the same issue. My Xbox crashed and now my games are corrupted. It's corrupted in the cloud and I've been trying to find where to fix it but its no use.

Please limit comments to providing new information that may help the developers find and fix the problem. Comments that do not conform to this rule are subject to removal. Questions and complaints should be directed to the Community Managers. Chatter and discussion with one another should take place on the MCPE sub-reddit or the Minecraft Discord.

My survival before corruption in 1.14 and corrupted save file

https://1drv.ms/u/s!ApZ00uy7DNfmhy0mTYGS-MLMQvNQ

Here are the game world files from our server. This server has never been upgraded past 1.14

Day one (No curruption)

https://adultscraft.com/downloads/tb.mcworld

A few months later with multiple areas of curruption.

https://adultscraft.com/downloads/doomsday.mcworld 

This issue is 7 months old, are there any news? Still happens on the latest version of Minecraft Bedrock PS4.

Also it happens on Xbox One too, add it to the platform issue too please

The bug tracker is staffed by community volunteers. We don't have access to Mojang's internal systems so we can't answer any questions about the status of a fix. For that, please contact Community Management. Thank you.

yeah same thing happens me too i play on a play station 4 and Yesterday because of a power cut my world i i have put so much effort on got deleted i even have auto save and everything 

do not expect any miracle regarding this problem.

In the past we where able to disable auto save, and save when wanted.

But now, quit your session, and make a copy of your world, and get back to your game.

Also, copy your saves on the cloud, or usb disk if no psplus subs

Can confirm in latest PS4 Bedrock update, long worked on World decided it wanted to corrupt most likely Autosave. Unfixable and had to delete losing all the progress that was made. It’s happened to me in the past as well. When will Mojang focus on more important things like preventing these Game-Breaking glitches.

Just for safety, and this applies to other thing that save data. Not just Minecraft. If you are on a laptop or mobile device, close out of the world/file when power outage. If on a desktop, buy a battery thing that keeps supplying power to your computer for at least a minute so that you have time to save and exit.

Note: This is NOT effective against crashes, so make frequent backups. Mojang will (hopefully) fix the problem.

while playing on my world in a minecraft on PS4, in my apartment it turned off the electricity and my minecraft world went wrong, and now I can't get to my world and shows me here from the date they are damaged, I can't restore them in any way

Thank you for your report!

This issue STILL exists, it always have been and I don't recall seeing an atempt to fix this bug.
Steps to Reproduce:
1. Force the power to turn off from the ps4 while playing within a world.
2. Play within your favourite world and hope for a random power cut, maybe from a storm, the ps4 will shut down.
3. Shut down your entire house's electrical power while playing within a world on a ps4.

Observed Results:
After turning the console back on and getting in Minecraft, clicking your world/save would showcase a menu telling you that the save file has been corrupted. Bringing it back is rather difficult as it requires ps+ to already own such save, or doing some tricks that hardly ever work.

Expected Results:
After turning the console on and clicking the world save file, it'll get in the world fine and you'd be able to pick up the game where you left from.

System PS4, Game version : Minecraft 2.48

Game crashed while saving IN GAME (bloody AUTOSAVE feature that you useless MICROSOFT developers should roll back) , world file got corrupted, when trying to load again the same world it start to work and get stuck indifinetely at 95% of " Generating Terrain" progress bar. No solution but to close Minecraft.

Copied version of the world : DOES NOT work.

Rebuild PS4 data base : DOE NOT work

Unistall / Reinstall the whole Game engine : DOES NOT WORK.

I'm quite hopeless that The clueless microsoft developers can find a way to fix this, they are just redirecting all the issues to this tickect, closing it and reopen it again. I will include here some key words, to appear in search (in the useless JIRA), so othe people can UPvote this funneled issue and maybe one day they come with a fix, or a workaround.

In the mean time, try to make backups, cause the file system management of Bedrock in PS4 is crap. To set up a .bak file and retrieve from the last .bak when the game crash is that difficult, Microsoft buying Minecraft.......and this is what happens. Shame on you MR Markus Alexej Persson, aka Notch.

And for the Jira mantainers , is a good practice twhen you redicrect another issue report to this one, and close the other (funny enough as resolved) to upvote this one by one, to leave that to non dev users is a really bad practice, if you would have done that , this issue would have at least 48 more votes than it has.

Same thing happened to me two days ago.  Thunderstorm turned our power off and back on.  My kids and I lost our world we had been working on all year,  Corrupted and Deleted.  I was (am) unable to get the world back and Mojang support is no help except to say "not our fault."  This would be true IF this was an issue for all games...except it's not.  

You guys really need to fix how the game saves. If I didn't keep creating a backup of my game saves after every hour of gameplay, I would have lost my 2+-year-old world several times.

Whenever there is a power outage, the game will ALWAYS get corrupted and be deleted. This never happens on any other game I have, just Minecraft.
I don't know what coding or protocol you use for Minecraft game saving, but it currently sucks. I have had to RAGE QUIT my game for weeks on end because I forgot to duplicate my game save after several hours of gameplay and builds, only to lose all the hours of work because the game save file gets corrupted and deleted after a power outage.

This isn't something new either. You all know that this problem exists. Why haven't you fixed this?

PS4, PS5 Bedrock. Current version.

Steps to Reproduce:
1. load world and play for several hours
2. Wait for a power outage - or pull the plug.
3. Try and load saved world, then Rage Quit game.

Observed Results:
Spend several hours building things, then the power goes out. The power comes back on and turn on the PS5 and loads the Minecraft game. Go to load the world file and get an error saying the file is corrupted and the file gets deleted.

Expected Results:
Expect to load Minecraft and up again and open the saved world and be back at the last save point.

More on this, just in case it might help IF anyone is watching this:

In line with MacBros just said 2 days ago, i quitted the game for a while and just yesterday decided to recover the last backup i had, fortunately i do back ups from now and then but still lost a month worht of gameplay. Anyway going technical:

This is for Bedrock in PS4:

When triying to retrieve the back up from the file on the cloud:

• You need to deleted the actual saved game, it does not overwrite properly over the same game with the same name. this might give you a clue to where the problems are.

• First i tried to just overwrite the file, it did not worked, FUnny fact, it seems to append both contents, the initial file was arouns 600mb, and the file after download the oncloud version weighted 1,2 gb, and still did not work, stopping at the same place in the bar as before (right after the end of it).

• Deleted the old saved game, and downloaded a fresh instance of the back up, and this time it did work. So actually the overwrtting from the cloud saved version did not work properly. that is something to look at also.

Please everyone reading this thread upvote the issue so the Jira does its job.

Please adiministrators of this Jira up vote this thread with as many inputs you have in the 30+ duplicated thread you have all around, so developers have a TRUE sense of how many people is pissed of. To close a thread and redirect to duplication without upvoting it subsequentially is a waste of time for all those people who wrote those 30+ threads.

This also happened to THREE of my worlds since I live in a country with frequent power outages. I constantly make backups, but I still end up losing my progress constantly if I forget to make a new backup. It corrupts the world and only gives me the option of deleting it. None of my other games delete my worlds in the event of a power outage i.e. No Man' Sky. The issue still exists in the latest version of Minecraft Bedrock on PS4 (as of May 5^th2024).

Still occuring in PS5 in the year of Luigi 2025
