Does this occur in vanilla Minecraft, without any resource packs?

Does the double chest cross a chunk boundary? To me the coordinates make it probable, and thus this bug may be MCPE-52790

Thanks for noticing the coordinates. However, even if it’s across a chunk border, the symptoms here are different than MCPE-52790. That bug has not been reported since 1.16 released, so I think was finally fixed with the fix for MCPE-78279. With that bug, the data for the contents of chests were lost. With this bug it seems that the chest contents are not lost, there is just an error with the blocks updating.

@Angus Miller: does the chest in the screenshot span Z = 351 to Z = 352?

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.)

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.

This is my friend's world so I can't really get a copy I can try and create a new world and recreate the bug on that one by setting up the same conditions. Then I can send that world.

I had also run into this issue.

Bugged chests can be found at: 787, 95, 1037

I already fixed some chests by breaking the invisible blocks and replacing them.

In addition, this is the log of BDS when the crash occurs

I have a similar bugs with beds. The bed was completely invisible until I broke it and placed it back. After I moved it 1 block, the bug stopped happening.

I had the same issue MCPE-107009 

I now have four double chests out of five that are showing this symptom.

My world is on Realms and you @Mega_spud are free to look at it if you like.

I’m experiencing the same issue on my realm however, it had nothing to do with nether travel and even attempting to break the chest crashed our game. I can’t open it or break it. The chest has been stuck like that for over a day.

I have experience this quite often and the workaround for this is just save and quit and join the world again. The chests will not be invisible. Sometimes it works, sometimes it doesn't.

I have found the problem (I think) the chest was on a chunk border and I solved the problem by moving it over by one block and now I don't have the problem anymore.

My double chests were also across a chunk line. It took a couple of game crashes but I finally got them moved.

If trying to break the chest crashes your game, you might try to recover your items by placing a hopper under the invisible chest.

I have also experienced this problem on iOS. However, I’m able to open the chests just fine (although, opening the rendered single chest only shows the first half of the chest and opening the invisible part of the chest only shows the second half of the chest). But when I try to take items out of either half of the chest, the items appear to go into my inventory but then go back into the chest.

I also have this issue happen when ever I leave the render distance and return. I found open them when not loaded cause the crash if items were in them.

Btw this also happens on 1.16.100.1I had the exact same thing happening to me. I was thinking of a way to solve it when a creeper just walked into my storage building and blew up half the chests. I was frustrated at first, but then I realised the creeper showed me the solution. I replaced the chests and that’s how I fixed the issue.

I have this problem but I didn't think a had a double chest there to begin with. I will make a copy of the world and try to mess with it for a solution.

If you right click on the invisible part, after it crashes your game, the chest re appears and all your stuff is still in it.

MCPE-108646 is a duplicate that I created before I saw this one.

I have same issue as well, with a large number of similarly placed chests (this fits to the hypothesis about the chunk borders). Half of each double chest has disappeared and an attempt to open the chest crashes the game.

We have had 2 reproduction, on a server. The first reproduction was the day the server was updated, Half of one chest was invisible, all contents were accessible in that chest, but one of the 2 double chests could not be seen. when the invisible chest was broken all of the items popped out and chest was returned. 

The second reproduction was discover about 1 week after update, This time the individual client that was observing the issue could not access the chests, they could not interact with the chests in any way. As an experiment a second person on a different computer came to inspect the same chest. All items were present. as an addional experiment the person who could see the chest flew away ~250 blocks on Simulation 4 render 16, The person who could not see or access the invisible chest logged out and waited 1 minute, then logged back in. This was an attempt to see if autosaving would permanently delete the items. Upon re-logging the items returned and the chests re-rendered 

This is an extremely concerning bug to everyone in our community as it very much resembles the tile entity deletion bug in 1.14 

We forgot to get pictures in either case. If we have another repro we will take pictures and document more completely.

From investigation into the "deleted tile entity bug" in 1.14 we had discovered that tile entities that do not have a data entry in a chunk seem to render as invisible. Speculatively data values from the server do not appear to be properly synchronized with the client that sees the "invisible chests" IE the data for the sub chunk containing the chests was not loaded or stored by the client.  

Items that should be noted to confirm the "client doesn't have the sub chunk data" hypothesis include: conduits not appearing, furnaces being inaccessible, beds being invisible, ender chests being invisible, hoppers not working, droppers not being accessible, barrels not being accessible, the item in item frames not appearing, signs not containing text an beacons not being accessible (for other people to note when they have a repro)

Clients were windows 10, 1.16.100.4
Server is BDS
Behavior packs are 1 player sleep (animation controller that calls time add 100 when in bed) and mini blocks (educational edition armor stands that are reskinned to look like blocks and companion spawn eggs)

Resource packs were not recorded at the time of reproduction, at least one person had a chunk border visualizer that showed the chests were across a sub chunk or chunk borders. however this person did not have the missing chests.

I, too, am experiencing this issue. Double chests have one of the chests invisible. When I open the visible chest, I see no items. When I click on the invisible chest, the game crashes completely. Logging off of the game & back on does not resolve the issue with the missing chests. This never happened in the years I have been playing Minecraft until after the latest update.

I'm sure I was annoying everyone on the realm as I tried to open this chest a few times in a row, crashing the realm each time. Sorry guys!  Breaking the chests did fix it, thankfully!

I am seeing this bug ONLY with large boxes that are in two chunks.

I think this started in 1.16.100. - But with all the other bugs it introduced in 1.16.100 it was a little under the radar. On the other hand it may have started to occur because I built up the chunks, placing lots of glass blocks which will stress the system. I only play realms so this may behave differently with the game hosted on a personal device.

One half of a Large Box does not always load if one half of the box is placed in one chunk, and the other in a second. It feels like about 1 in ten chance, but not keeping a real good record. Accessing the box (when bugged) will often cause a crash of the game on my IPAD (which may be related to how full the box is), but not a crash of the realm. Work around is of course to not have boxes located in two chunks.

This can often be fixed by running far enough and coming back that the chunks to reload. Or doing anything else that causes the chunks to reload. However it can happen several times in a row.

To replicate probably the quickest, after placing the large box in two chunks build a portal and go in and out of the nether. 

To visually see the bug easier place a item frame on each end of the box. If the half of the box it is attached to does not load you will have a item frame floating in the air not visually attached to anything. When it occurs this will not occur with just one box, but all boxes straddling the two chunks.

I can concure what Dan Brady is describing exactly. Except I'm playing solo Android MCPE. So I just save and quit. I haven't checked the amount of items in all the double chest. But just glancing at the screenshots I posted. I know the double chest with the water bucket on the item frame has only 3 or 4 in it, however the double cheese with scaffolding on the item frame is almost completely full. So quantity may not be a factor. I'll post the world download in a little while, not able to at the moment.

I had this happen on my Xbox running version  1.16.200. I hadn't noticed this bug when running 1.16.100 after many, many hours of gameplay though I did have issues with invisible mobs and mobs freezing like a lot of other people. Lucky me that I finally see this bug on the update! I'm now watching out carefully for invisible chests until this bug gets fixed.

We're experiencing the same issue on a BDS. Sometimes chests have items in them, sometimes they're empty, but every time they crash the server if someone opens one. I have to go into creative mode to delete the chest. Thankfully any contents inside are not lost during the process. We crashed twice in a row yesterday. Please fix asap.

playing on a server using a windows 10 computer. found my chests that spanned a chunk border to be broken. opening chests crashed the server. We are running on the 1.16.201 hotfix that was said to have fixed this issue. 

Another player today had the same issue and crashed the server twice before realizing the cause. 

@Caleb Johnson: If the chests were affected before the 1.16.201 Hotfix then they probably won’t fix themselves. You will likely need to break and replace them, and then they should not glitch again.

So we've had this issue occur with a storage system on a 1.16.200 private server. With a mix of chests crossing the chunk boundary variously broken and not broken, handy.

The actual cause of this issue is that the double chests are (somehow) losing their pairing coordinates, TBH I'd be curious if the cause is tangentially linked to the villagers on chunk boundaries dissappearing issue.

Anyway, depending on the chest it looks like they either completely lose the pairing coordinates or they're reset to 0,0. The side that loses their pairing coordinates remains functional as a single chest. The side that references 0,0... crashes the server. For my amusement, I placed a chest at 0,0 at the same Y height and... it still crashed. I'm guessing because that chest didn't have the required backreference pairing coordinates to the other chest.

Once 1.16.201 is live, we'll break and replace the chests and report back on if the issue reoccurs or not.

EDIT: Apparently 1.16.201 has been live since mid-December.... our hoster hasn't released the update for the server yet, yay....

BTW this is what a working double chest looks like, well, half of one.

@Azarel Out of curiosity, what would happen if you added the doublechest tags for the chest you placed at 0,0?
