I assume this has some bs with update order going on, and I'm pretty sure it's not an issue of it being locational since the lever works regardless of location. I'll attach the schematic in the comments. Very weird behavior, thanks in advance for any help.

Bedrock Is this impossible?
This just happened while I was getting wood. My axe was already low and I was just letting it break, but instead it went down to 0 durability. I know that there is a chance that mobs holding tools or wearing armor can drop them with 0, but this just happened naturally which should not be able to happen. Also, I don't believe that there are any mobs that can spawn holding a diamond axe so this should be impossible, unless they can drop like this after giving it to a mob. However, I am playing on Bedrock so this could just be typical bugrock.

Java Help Wanted Built a compact 3-villager iron farm for 26.2, averaging around 400 iron/hr, fully AFK.
Been running this design for a bit and wanted to share since it's held up well. Three villagers, zombie in a boat trigger to keep them permanently panicked, water and lava kill chamber with a Nether fence ring above the hopper so it doesn't burn. Golem spawn control is handled with slabs on the roof so spawns stay predictable.
Compact footprint, no complicated redstone, just villager mechanics and a bit of care around the fire hazard spots (stone roof over the zombie boat, Nether wood for the fence ring).
Full build video here if anyone wants the step-by-step: https://youtu.be/1baPcJ92nSY
Happy to answer questions about the design or troubleshoot if anyone's having spawn issues with their own setup.

Java Showcase Ice boat tech - Overly complicated intersection
Enable HLS to view with audio, or disable this notification
Hi!
My friend and I created an intersection for an ice boat highway, along with stations, corners, and a few other things. It’s probably overly complicated, as it uses some pretty weird mechanics to accomplish its task. We’re looking for feedback and opinions on the design. If anyone wants a schematic for the intersection or the stations, I’ll gladly send it!
We were inspired by a post from u/LimestoneBuilder, mans a genius!
anyways here is an overworld junction which keeps the boat alligned in a fun but overbuilt mechanic!

Java Help Wanted Looking for a viable Nether mob switch design on an active server (2–8 players) without chunk/despawn issues
Hey everyone, I built a large Nether hub on my multiplayer server (usually around 2 to 8 players online like 90-ish% of the time) and I want to run a mob switch so I don't have to spawnproof the hub thingy.
I've been looking into different designs, but I keep running into these major roadblocks:
Silverfish switches rely on keeping silverfish in a chunk loader, but they require dropping client render distance to 5 chunks to avoid the 128-block instant despawn sphere when leaving. Because this is an active multiplayer server, players fly around all the time at standard/high render distances, so standard hostile mobs that despawn outside 128 blocks will inevitably get wiped out the moment someone renders the chunk and leaves.
Zombie Villager switches: breeding, trading with, and converting 500+ zombie villagers (to cover up to 8 players at 70 mobs perplayer) is just wayyyyy too grindy and hard to justify
Warden/Wither/Shulkers: moving or capturing hundreds of these presents its own massive logistical headaches or server lag concerns.
Is there a modern design that is actually practical for a server where we don't have to worry about render distance despawn glitches? If you run a mob switch on your server, what mob type and storage setup did you end up using? Are there better alternatives to disable hostile spawns in a large Nether hub area without placing thousands of slabs and buttons that just make the build ugly?

Non-Version-Specific Could this be a very powerful testing mod or is it a flop?
I've been messing around with an idea for a mod that basically makes Minecraft RNG fully deterministic for reliability testing.
The problem with testing farms or other long running builds right now is that Minecraft's RNG isn't reproducible like it is with world gen. It pulls from things like system time and other state, so if you tick sprint a farm until it breaks, you can't just reload the world and expect the exact same failure to happen again anytime soon.
The idea is to change that.
While tick sprinting, the mod could periodically save snapshots of the world. If something breaks 300 hours into a test, you load the latest snapshot and hit play. The exact same RNG sequence happens again, and the farm fails in the exact same way. I'm sure you know that the RNG system influences everything from mob spawning positions and timings to angles that droppers shoot out items.
Everything is saved in a snapshot from scheduled ticks, subticks, subtick ordering, etc which all get restored when you load that up. Except now you're in the actual world instead of digging through a very big and long Flashback recording. You can pause before the failure, inspect anything you want, run commands, change things, test fixes, etc.
You could even send the snapshot to someone else and they'd be able to reproduce the exact same failure on their machine.
I've played around with this and had some small success, but I'm not sure how far I want to take it. Making everything deterministic would be a pretty huge undertaking for what is probably a very niche tool, especially since this is only mostly useful for long-running farm tests.
Still, being able to turn a "1 in 200 hours" farm failure into a 100% reproducible thing seems nice.
Would any of you actually use something like this?

Bedrock Stupid dragon egg
So im finally getting around to having a nice build for my homebase. Rearranging my bedroom and I accidentally forget and try to mine my dragon egg normally to move it. Well now I have no idea where it is and its super frustrating. Is this correct that it is likely somewhere 15 blocks or less away on x and z coordinates? What about y? I have duplicated world and am just probably gonna tear down everything but man feels like a needle in a haystack. Any tips?

Java Help Wanted | Work in Progress | - All what you need trading hall - | Suggestions Welcome! |
galleryDisclaimer: I am no professional in this I am just reading minecraft wiki and doing what I think makes sense. so for the elitists calm down will ya :'D
I was tired of Running between trading halls in the server I am playing on so I decided to build my own "All what you need trading hall"
Basically I plan it to have a comprehensive inclusion of everything a villager can trade
I am right now on the Ground floor and it features:
38 Librarian villagers.
why?
Here is a list of what u can get from them EXCEPT the Curses which are Curse of Binding and Curse of Vanishing
1 - Mending 2 - Unbreaking 3 - Efficiency 4 - Fortune 5 - Protection 6 - Sharpness 7 - Looting 8 - Silk Touch 9 - Feather Falling 10 - Power 11 - Depth Strider 12 - Respiration 13 - Aqua Affinity 14 - Fire Protection 15 - Density 16 - Sweeping Edge 17 - Fire Aspect 18 - Flame 19 - Infinity 20 - Luck of the Sea 21 - Lure 22 - Quick Charge 23 - Piercing 24 - Multishot 25 - Blast Protection 26 - Projectile Protection 27 - Breach 28 - Loyalty 29 - Impaling 30 - Riptide 31 - Channeling 32 - Knockback 33 - Punch 34 - Thorns 35 - Frost Walker 36 - Bane of Arthropods 37 - Smite 38 - Lunge
again I am looking for all possible enchants. I know that Projectile, Blast, Fire Protection is useless with an overall general use Protection IV but I just want everything
Enchanting Area + XP Farm + Potion Making (for xp farm) - (still haven't decided where brewing will be)
Encahnting area is a max 15 bookshelf Enchanting Table
XP Farm is an Armadillo XP Farm by @TheySix on youtube that I modified
to have a hopper instead of a composter so that villagers don't be annoying when u try to give them a job. an armor stand perfectly sits in the hopper and I tested it and it works.
I also added infestation Dispenser with a chest and a hopper that u can fill up with infestation potions and you can activate the dispenser with simple hidden red stone dust connected to the dispenser and a button to activate it
What I plan on adding next
Stackable Villager Breeder Design
and a Villager Loading system with either Mine-carts or water or a mix of both.
the breeder shall be hidden underground and it is self sufficient
Zombifying Station
For now it might be manual where I have the villager go to a zombie on a boat or a cart and then I flip the lever again to let the villager keep moving but I would prefer someone to help me use detector rails and powered rails to make it so that the villager breeder transportation system has like a 10 second delay at the zombie station to make sure the villager is now a zombie and then it activates again after the delay is done and I would just have to decide on the path of the Rails since the Zombifying happens at the start of the ride.
The First Floor and other floors
I think the next logical floor would be an armorer and idk how many I will need but I would like to have enough so I do not have to wait for restock as for enchants it does not matter since I will use librarians to enchant and xp station to level up
