invisible shulker box that crashes the world when you break them

Editing the world with UME/Toolchest and adding shulker boxes with the same coords as the invisible shulker boxes in the tile entities part of the chunk allows the shulker boxes to be visible and broken.

Editing the world with a third party application shouldn't be required. This is a bug report, not a help request.

I was just letting the dev know that shulker boxes are present in the block data of the chunk, but not in the tiled entities, and that's what is crashing the game.

I also found three invisible beds in the leaf-covered cobblestone building beside the invisible shulker boxes.,
Also, the block data shows a "piston arm collision" in the palette. That's an invisible technical block that I'm not used to seeing in a saved world, so I'm wondering whether you might have used some unusual technique with a piston in the area that might be involved with creating these strange blocks.

Understanding how this happened might require looking at how these blocks were upgraded as 1.13, and possibly older releases, opened the world in turn. How far back do you have backup copies of this world? Also, there are a lot of player profiles recorded in the save, which tells me it might be hosted on a server. Is it from Realms or the Bedrock Dedicated Server, or do you just have a lot of friends on Xbox Live playing it?

Hi,

The world if from a realm. The earliest back up I have of this is June.

The world I uploaded is truncated, I removed nether/end and reduced the overworld, the original file is 500MB and backups are larger. I'm not sure how I could make them available to you.

Are piston arm collision in the same chunk ?
I don't believe there ever where pistons in that chunk.
There was invisible chests too. I broke them before crashing the realm.

Let's worry about the backup size if we decide we might need one.

Actually, the piston arm collision was probably me. I tried to move them with a piston to see if that would make them visible without crashing. It extended, but it didn't the boxes or make them visible. I broke the piston after it didn't work. The shulker box that was there but wasn't there is probably why the collision block
wasn't removed when it should have been.

I'll confirm this and let Mega Spud have a look at it.

Directions to replicate this glitch may be beneficial.

I may able to provide more detail about this. (Although I know it will be fixed in 1.15).

To other person that meet this issue:

Currently I didn't find a way to restore those blocks, but the can be removed by getting pushed by pistons. (shulker boxes would be replaced but chests seems would not)

BG info:

I own a server that runs on 1.14.60. And some of my friends use piston+furnace to duplicate items today (Take items in furnace at the moment it is pushed, you would duplicated those items).

What I found with those some invisible shulker boxes, chests and signs:

• The outline(border?) of those are still the same (known from signs);

• the particle colors are remain the same with the origin blocks when I try to destroy those blocks by hand;

• the blocks will disappear after a piston pushed it (with air at the other side which make it pushable);

• crash logs at background shows that the server knows those blocks.

  • e.g. Crash: at ShulkerBoxBlock::playerWillDestroy[Player&, BlockPos const&, Block const&] const (UnknownFile:?)

Since both the cause and the result are related to block data, I guess this may be caused a memory leak issue?

Resolving issues that were marked as fixed in the 1.15 and 1.16 Betas, now that 1.16.0 is being released.
