As of 2025 I have now deleted my beloved world as I could not look at that greyed out version anymore. It was also taking up “ save space” once again so I dreaded the “can’t save no storage space error” popping up again and ruining another world. I wish wish you all luck with your worlds.

I had the same issue with my 1.9gb world. Through hours of research I finally was told there is a 4 gb limit of “save data” allocated to console world size which includes the base game and any saves.
This info is not openly out there, in fact it’s downright impossible to nail down but I did get this answer.
After deleting every save I ever had I finally got my world to open in the 1.20 update… the kick is it can never “ save” a play session as there is not enough space.
So much for infinite worlds.

This bug is also happening on Xbox in .20. I made an end map about a month ago and last week a circle of overworld popped into existence on it… the next day there were 2. My report has been closed and added to yours.

 This is an Xbox world realm btw.

The cauldron are now collecting snow and it is also building snow in layers as it is meant too. Thx for the fix.

Hi tried it again and it now works in 1.20.22 snow is collecting in the cauldron and building up in layers as it is meant to. Thx for the fix.

I also tried making a “new” world as I have nothing on my list now except one unplayable world and only my realm world. The game just crashes then I get error out of space again and again and again

Tried to load minecraft yesterday…back to Xbox can’t save data messages even before the game loads. If the mythical 4gb limit on Xbox x is the reason, why does my game manage file say I only have 3.2gb in total?

Since they keep “ closing” reports I will add my comment here.

Xbox game data on failed to sync worlds is being added to my world save data file and causing errors out of data storage space on both xbox and minecraft, I have 1 realm 1.2 gb world I can sometimes get into and 1 unplayable greyed out world ( my original 9 year old world ). This load will not sync as it gets to 99% then just crashes the game, however I can fully load and play my world on Xbox preview with no issues.
My game in manage games balloons from 3.4 gb to over 11 gb without any game play, it just goes back up/ down without any action from me.
I am again getting constant can’t save data messages.

This data replication is a bug and was reported by me in my previous bug report. It was closed and put into this bug report as a duplicate issue.
I am not doing anything with the game to cause this data save error as it started immediately after the October update and randomly happens if I either try to sync a world ( I now only have one on my list but it is greyed out) or I enter my realm then save and quit or I try to make a “ new” world. All of these produce the random extra data and I end up deleting minecraft and reinstalling just so I can get into my realm which is only 1.2gb.

Hi Jeff if only that was the case. I have NO other worlds only one unplayable version of my old world and one realm world. Nothing else. I do not have multiple shader packs nor adventure worlds. The only one I have is the texture update pack which is tiny.
It does not explain why one day my Xbox data is 3.2 gb then the next it skyrockets to over 11.8 gb without any sort of play by me.
Explain that…

As a side note I spent over 9 hours with Xbox support trying everything possible to try to save my minecraft world. Resetting, hard factory resetting, deleting everything including saved games, you name it I did it. I striped my Xbox down to the operating system and this crap is still happening. As Xbox support have said multiple times it’s a developer issue not an Xbox issue. The game saves are being “ cloned” in minecraft saves then updating the gb value onto the Xbox cloud save. It’s a vicious cycle which seems to not be being addressed.

I have been having this “cloning data “ issue since the October update on Xbox. Not only do I get the Xbox is out of data space but also the minecraft is out of data space errors.
I now only have one unplayable world on my list and one “sometimes” playable world in a realm. I can not even start a “ new” world as I immediately get the above errors!
Watching the minecraft “ saved data” in manage games on Xbox sees it randomly fluctuate between 3.5 gb up to 11 gb of data without having any worlds able to be played.

As I have asked before “ what is this data?, where is this data? and why is this data? … no answer.

This is ridiculous as it is NOT being addressed nor has anyone been assigned to this Xbox issue. They obviously don’t care.

Same issues nothing will sync. Can not play any old worlds or even start a new one in my Xbox minecraft game as I get the error messages about no space on both Xbox and minecraft.

I have one very old version of my world on a realm and I can not download this world as I receive the above messages. My data on Xbox is wildly jumping from 11kb one day to 3.2 the next.

This is BROKEN!

Unfortunately for me I haven’t played with anyone else or in their games so I do not know where this data is coming from. I only have 2 packs of textures and no other downloads. I see players with hundreds of worlds and they have “ space” . My previous minecraft before the “ update” had over 10.8gb of saved data. Now if mine goes over 3 it basically crashes with those errors. That’s stopping me from downloading my 1.2gb world from my realm.

If I try and sync the only one greyed out world I have left which was my main world and the only world I played ( it gets to 99% then just says can’t sync) then I get the minecraft is out of data message…followed by the Xbox is out of data message can’t save can’t play.

I have a very old version of this world on a realm and can play it sometimes and if I try to download it i start getting the every error messages all over again.

I had no problems playing my old world at all before the “update”.

I now can only play on my realm world. If I try to even sync an old world or even make a new world I get the minecraft is out of data error message followed by the Xbox is out of data message…again. I can’t even download my world to the regular list as I immediately get the errors even though I have zero worlds on it.

No I play only play survival so do not touch the menu options. I have collected powdered snow previously in the exact same spot on the 1.18 build. Since the 5/10 update nearly everything is broken on Xbox.

Tried minecraft preview. My original  world loaded very quickly and with absolutely no issues…until I quit out. 
Then the wonderful minecraft can’t save your data as it’s too full messages raised their “pretty” little heads again, closely followed by the Xbox is too full issue again.

In the original minecraft I have NO other worlds in my list except 1 greyed out version of my original world which I can not play because it will not sync.

What is all this “data” and why is all this “data” and where is all this “data” ?

Today my only Realm world now requires a texture pack download, then proceeds to take about 5 tries to load. Two days ago I downloaded the realm world to my main list… it now fails to load and experiencing the minecraft is out of data error all over again. The load is not greyed out but will not load due to this error… it is the only non greyed out world on my list as everything else failed to sync.

My realm which has the only old copy of my world which for the last 5 days have been unable to load (pink / black minecraft is out of save space) loaded today and now it’s messing with textures. Blocks of coal now look like glow stone. And the game crashes after I quit out. Texture  packs are flashing between pink/ black and the normal pictures.

I know I should stop trying but…
