Missing BlockEntity (Piston_Extension, ...)

Note from the moderators

This ticket is for crashes on vanilla clients and servers only.

As a workaround, you can play on 1.10 for now: Start the launcher, select Edit Profile. In the Use Version dropdown menu, select release 1.10. Then click Save Profile.

Ways to reproduce:

Confirmed: Piston extensions, for example placed on their own for decoration using /setblock ~ ~ ~ piston_extension
Confirmed: Flower pots placed in worlds created in 1.6.4 or older, even if the world has been opened in versions > 1.6.4 (MC-103992)
Unconfirmed: Command blocks, world download sent to @unknown according to MC-104216

Hi, reopened this since it's actually on a vanilla server.
Is this on a realm or a standard server?

migrated

This time, the Block Entity is a Piston Extension:

A detailed walkthrough of the error, its code path and all known details is as follows:
---------------------------------------------------------------------------------------

– BlockEntity missing instance data –
Details:
BlockState: minecraft:piston_extension[facing=west,type=normal]

migrated

This is a standard server. Sequence of events this morning. Launched minecraft. Crash. Grabbed Server download (unknown if any code change in 1.10 vs. 1.10.1) and launched new server. Crash.
Server is pure vanilla, can pack up and send the server folder if it would help. Game world that is being used was created as a single player several? years ago then started using it for out in house multiplayer server.

migrated

I recieved the same error on multiple singleplayer worlds, once I switched back to 1.10 everything worked great again.

Happened to me on a realm using the 1.10.1 client, attached the crash report.

Curiously, using the 1.10 client works without problems (though I'm mostly surprised that it works at all, as realms previously always forced me to use the latest client).

migrated

This Block Entity is a Sticky Piston.

– BlockEntity missing instance data –

It should be worth noting that in other tickets, some of these had to do with chests, and one actually had to do with an Ender Portal block. However, I cannot remember if they were vanilla or not.

migrated

Has to do with flower pots in my case.

Seems to be the 1.10.1 client that has the bug. (Mac in my case).

I upgraded my server to 1.10.1 (from 1.10) and still get this crash on the client. No errors appear on the server.

Setting my client Profile to 1.10 (Minecraft Launcher -> Edit Profile -> Use version) lets me log into the server with no problems.

Setting the client Profile back to "use latest version" (i.e. 1.10.1) and reconnecting to my server causes the crash.

Now there's a popup saying "If you were trying to play on a multiplayer server, please contact the server administrators." That's not much help, seeing as it's nothing to do with the server. 😞 Or are server admins expected to search the world for every sticky piston manually?!? :o)

migrated

Probably not a surprise, but this happens on my Linux client as well. Gentoo client on JRE 1.8u92, Ubuntu server on JRE 1.8.73, issue started on upgrade to 1.10.1, upgrading server didn't help, relaunching client as 1.10 seems stable.

migrated

Getting the same issue. Says:

– BlockEntity missing instance data – Details: BlockState: minecraft:flower_pot[contents=cactus,legacy_data=2] Block coordinates: World: (291,70,582), Chunk: (at 3,4,6 in 18,36; contains blocks 288,0,576 to 303,255,591), Region: (0,1; contains chunks 0,32 to 31,63, blocks 0,0,512 to 511,255,1023)

Downgrading from 1.10.1 to 1.10 fixed this issue for now, but not sure if its going to be an issue going forward.

My minecraft just crashed and directed me to this JIRA issue. I think this must be the first time I've had a crash direct me like this. I had an identical crash earlier, except that time it didn't give me an error message directing me to this JIRA isue.

Anyway, running a vanilla client connecting to a locally hosted vanilla server (both 1.10.1).

I'd like to note that this issue does not seem to be consistent. I've been building in an area away from my main base, and the game works just fine out there for hours on end. I come back to my main base to drop off mined material and pick up other stuff, then head back out. So I've been back to my main base 5 or 6 times in the past few hours, and I've only crashed twice. Both times it said it was due to a piston. While I have quite a few pistons around my base, only a single set activates in an automatic mechanism, and tracing the co-ordinates of the piston listed in the crash report goes to one of these pistons (used in a pumpkin auto-harvesting machine).

migrated

But I can't use Realms on 1.10...

The issue seems to be caused by looking at extending/retracting pistons from far away, in creative mode in my case (I was building a redstone printer with pistons).

migrated

I believe it's long distance usable blocks in general, considering I've seen crashes that involved chests and even an Ender Portal block.

Hello everyone!
Had the same thing happen to me on both a newly created 1.10.1 single player file as well as a 1.10.1 realms file in vanilla. Installing a command block creation would cause it to crash, and on realms, would give the same error to both me and my friend on the server. Got the error codes MC-103978 and MC-103981. Changing your client to 1.10 rather than 1.10.1 resolves the issue, both for single player and for realms servers. Allowing the world to render prior to installing the one command creations did not resolve the issue in 1.10.1. Crash report always reported a missing BlockEntity.

Did a test where my friend was able to be on the server with the working command creation in a 1.10 client (on realms) and it worked perfectly fine but when I went and changed back from 1.10 to 1.10.1 and got on, it would crash. Something in the 1.10.1 update is causing the issue, preventing people from getting onto their personal servers as well as multiplayer servers. ONLY WAY TO RESOLVE CURRENTLY IS TO CHANGE CLIENT TO OLDER VERSION OF 1.10. Hope this helps!

A (Repeating) Command Block this time?

I am most certainly convinced this is from usable blocks.

It seems to be block/tile entities generally.
In my case it's so far CommandBlocks, Beacon, Chest, Sign, Flowerpots, Comparator, Dispenser, Jukebox, Piston extensions (also with no pistons present, just the technical block itself).

Everything was already placed in pre-1.10.1 worldsaves. I did not try yet to reproduce a crash with newly placed block entities.

Note: If the crash causing block entity is a CB, then (at least in my case) if it contained data such as a command inside, then this command will be erased, not the commands inside the other non-faulty CBs in the same worldsave though.
I went from 1.10.1 back to 1.10 to delete a faulty CB (to see if it fixes it or if there are more faulty CB), and when I checked the faulty CB in 1.10, the commandline was empty.
This happened to all CB, and I'm 100% sure there were commands in them before.

I'm not sure yet if this applies to all faulty block entities.

Ok, i dont use JIRA too much but my ticket sent me to this and i have crashed several times in 1.10.1 with newly placed command block and pistons. The command block has a /tp @p ~ 200 ~ and whenever the piston is retracting while i teleport it crashes. Hope to be of help 😃

Edit: also, this happened on a singleplayer map of mine

This little "machine" causes me to crash when I relog. If I build the exact same machine but without sticky pistons, I can log in to the world.
