[MCPE-168969] Falling through solid blocks at Y=255

I'm building a structure at high altitude (Y=255), and I'm suddenly falling through the blocks. This seems to occur when I'm standing on a wool block with nothing underneath it. Attempting to place blocks also results in the block disappearing and returning to inventory. Replicated on both online and local worlds.

Hello Mengarda85,

I am unable to reproduce this bug.

Can you please provide more informations or steps?

Do you use datapacks on your worlds/servers?

Thank you !

Mengarda85 2023-03-27T07:08:21Z

Hi,

Not sure about the datapacks thing, my friend hosts the world on an external server called Shockbyte. However, I have been able to replicate this error on local worlds on both PC and on MCPE on Android, so the server wouldn't be the issue. I go up to approximately 255 on the Y axis, make a wool platform, and when I step out to place blocks further out, I notice the air supply meter flash up and disappear. As in my attached .mp4, when I eat, my character's location changes slightly (enough to clip me through the platform). In a similar area, I had also died while standing still with the game telling me I "fell from a high place". I will see if I can capture these things happening and attach the videos when possible.

Hello Mengarda85,

Is your friend able to see the blocks you have placed? Are you sure that the blocks have been placed? I've tried for a few hours to reproduce the bug on Windows/Xbox/Nintendo Switch yesterday, but i wasn't able to reproduce the issue !

Thank you.

Mengarda85 2023-03-27T07:38:18Z

I've added a few more example videos. Hope this helps pinpoint the issue.

Mengarda85 2023-03-27T07:39:49Z

I will try to get him online to witness the glitch as well. It's been typically only me on this structure at that height. This doesn't happen on lower levels for me or anyone else.

Could you please attach the world here to the report, if the world exceeds the 10 MB limit you can upload it to any website and link it here in the report.

As requested, please attach the world to your report.

I have this issue as well, but mines with Terracotta blocks. They have to be a single layer of blocks at y >= 255. I play on Windows 10 edition with no datpacks and was even able to do it in a new creative world when I built 5 block long platforms at each y level to verify where exactly it started. I attached a screenshot of the issue not being present at y = 254, but being present at y = 255.

Once I placed blocks, I started to suffocate, had issues placing and mining blocks, and fell through when I ate food.

Mengarda85 2023-03-31T00:40:15Z

I have noticed that this error seems to only affect this specific height level, between 255 and around 257. I'm working on Y 259 (after some VERY frustrating workarounds), and it's no longer affecting me. I got one of my friends to record me while the glitch occured as well, and it also affected him. I will upload soon.

Unfortunately, I do not have the world to upload and my friend can't get it to me at this time.

Mengarda85 2023-03-31T00:42:07Z

I should also add, I have updated to 1.19.73 since lodging this ticket, and it's still doing it.

Raziel0 2023-04-06T01:22:20Z

Having the same issue in my world.
Height does affect whether the bug is present or not, 255 as well
The issue seems to happen in specific blocks only, eating clips you through the blocks affected by the bug
Apparently carpets and slabs over the block that's bugged are not affected by said bug. This also applies to redstone, one redstone is placed over the block, standing on it doesn't cause any damage

This affects all levels, but it seems to happen more around 255-256.

Same issue 1.20.12 hotfix on Android One UI 5.1.

Player takes suffocation damage while standing on the edge of a block at Y255. The player falls through the block after eating at Y255. After closing the game at Y255, the player spawns at a lower Y location.

I experienced suffocation damage while wearing all iron armor, a shield, and being crouched. I seemed to only take this random suffocation damage when above Y level 255. At least I assume that is the case judging by what comes up on my screen. I see the air bubbles pop up for a split second above my hunger meter while taking the damage. They are all small and not the full air bubbles. The whole bubble bar shows up like this and goes away quickly after the damage occurs. Sometimes it happens only once, but other times it persists until you die. Whether you stand up or not doesn't matter if it decides to keep going. Not even falling all the way to ground level solves the problem. It seems as though it occurs more often while crouched, but I have had this to happen on occasions while not being crouched. I have tried taking off all armor, removing my entire inventory, and nothing seems to remedy this problem. I have also tried this on multiple worlds on PS4/PS5. It persists on all old/new worlds. This has been happening for several months now. Is there any work on a patch for this?

Shadowkitten47 2023-09-27T00:55:39Z

Affects 1.20.30
Food Will Make you fall (As showed in one of the clips of this post)
Right-clicking tools half stick you in the ground ( As showed in a duplicate report )
Also found out that changing using the timer function in horion ( don't ban me lol ) if you decrease it will cause you to fall more often and the opposite.

only worked for me if I left and rejoined

Yes @unknown, They still an issue in latest Release (1.20.50)

I'm on version 1.20.51 and have recently experienced a bug that this tracker has listed as a duplicate of this one. Taking damage at Y 255 when placing blocks, interacting with blocks, or even right clicking with nothing in the hand. Also happens if I break blocks. It does not happen if I stand and do nothing or stand on a pressure plate to interact with a trapdoor (so long as I haven't yet placed, broken, or interacted with a block, unless I have just stepped up or down one block which seems to 'deactivate' it, just to clarify), and it stops happening when I move up or down one block. Also, it seems to start and stop causing damage when I move forward and backward, appearing to only effect some blocks in front of and beside where I was at in the building I was in. I also have a map in my offhand and have noticed the location indicator moves repeatedly when the issue occurs. I have taken videos of me playing with the bug to see how it works, but I do not know how to upload it here, or what the maximum file size limit is.

I am on bedrock version 1.20.51 and am also experiencing this issue. I have a structure built on a realm I play on, and while standing at level 255, if I perform any action that requires a right click, I begin taking damage. Air bubbles appear briefly, but disappear. The damage stops if I move out of the area or jump. If I eat food, I will drop through the block I am standing on (an iron block) and drop to a lower level I had to build to prevent me falling all the way to the ground. I first learned of the issue because I was exiting a nether portal at that location and when spawning in, either when exiting the portal, or loading the game at that location, i was dropping through the floor. I also have the periodic issue of placing blocks, but they flash on screen but then disappear as if I hadn't placed them (item is back in inventory).
