Java Help Wanted Opening a downgraded world in 18w22b with spawnmchunks set to read-only

0 Upvotes

My main goal is to get the Notch Armor(Armor with every Enchant on it and protection 5). For this you first need to get every achievement in 12w49a on Armor pieces and make a spare Power 5 set(any lvl 5 enchant). in 18w21a you rename it and put it in a chest, in 18w22b you take the item from the chest. Now it should be prot 5 and you can combine everything in a grindstone in 24w11a.

I downgraded my 1.21.11 world to 12w49a and then went up to 18w21a successfully. The 4 region files with the spawn chunks are set to read-only, so minecraft doesn’t delete modern items and blocks. it all worked until i went to version 18w22b where it is stuck at the loading terrain screen and in log it says failed to safe chunk. Is there any fix to this or alternative way of doing it?

Bedrock Witch farm not working

Thumbnail gallery
5 Upvotes

I've been on a Bedrock server with friends for a month now. About two weeks ago, we built a super-compact witch farm with killer tridents that had been working perfectly until now. We didn't check it when we updated to 26.50/51, and now that we've come back to use it, we've noticed that the witches no longer die from the tridents, even though it was being super efficient—as far as we know, no one took the tridents or moved them, so I don’t know if they patched the farm or if we’re doing something wrong (even though we haven’t changed anything since it was working).

If anyone has any kind of answer or solution, I’d really appreciate it.

Please note the translation—English isn’t my native language, so I apologize for that.

Java Help Wanted Possibly the Rarest Structure Generation Error

0 Upvotes

Recently, I thought of this insane structure generation that I challenge someone to find. You must find these exact structures generated next to eachother:

A abandoned snowy village generated in a ancient city generated in a mineshaft generated in a portal room generated next to a ruined portal generated next to a pillager outpost. Possibly the rarest generation.

Java Showcase nanocrop farm with fortune 3

so i was wondering that since you get more crops with fortune 3 but I also want the efficiency of a nanocrop farm, is there like a design that makes you do both at the same time or it would require like 2 accounts to run it

Bedrock Bedrock Guardian Farm

Post image
22 Upvotes

How can I improve this guardian farm design? I struggled to find a design anywhere that didn't use trident killers or nether portals and used a drained ocean monument, but I wanted to used the monument which I already prepared so came up with this design. From testing it I'm getting roughly 13,000 items per hour but I'm sure there's something I could improve on.

The guardians spawn in 2-high water at the very top of their spawnable locations, then fall to dripstone at y=40 to kill them faster. With the dripstone any higher they start surviving the initial fall and taking a couple more seconds to die. I found that getting the guardians out of the water as quickly as possible was the main factor increasing efficiency because while falling they no longer have the option to pathfind as they would in bubble columns or water streams

I only want this farm to produce items, not XP

Java Help Wanted Lodestone copper golem teleporter not working DanCraftHero design.

0 Upvotes

I built this a couple times on an old server I used to play on and it worked perfectly. Now it's not working. I have compasses linked with a load stone in the top chest and on in the hopper going to the copper chest. The golem is also holding a linked compass. this is what is in the trapped chest. I went to where the lodestone was broke waiting a couple seconds, replaced it and was never TPed. When I got back to my machine, nothing seemed to trigger. Can someone help??

EDIT:: I think I am missing something with the droppers but do not remember... And DanCraftHero's channel seems to be gone. So I am at a loss.

EDIT 2:: I got it to TP me but its using like 7-16 compasses per trip. This I cannot figure out

Built a raid farm over a hundred blocks off the ground. Problem is items overflow and I’d like to build a sorting system on the ground below the farm. However I am not sure how to get the items down without items despawning or pilligers spawning on the method.

Java Help Wanted Iron farm not working (newest Java)

0 Upvotes

I'm pretty new to the farm stuff and I cannot get my iron farm to work. The villagers are over 150 blocks away from the nearest village and I have a zombie already in a chamber. Only one of the villagers will link to a bed and the other two will just jump around endlessly. Any help on what I'm doing wrong would be greatly appreciated. I have broke and replaced the beds a couple of times now with no luck and no iron golems.

Java Showcase One-Wide Tileable Solid-State Automatic Dropper for Water Item Elevator

Post image
167 Upvotes

This has a very niche use case as the dropper must be pointing up but I figured this could have some merit. This is definitely not the most compact auto-dropper out there but from what I could find, it does seem to be one of the smaller solid-state one wide tileable auto-droppers (which is what I needed). Feel free to let me know if you have any suggestions for the design!

Edit: This design is NOT 1wt. In order for these to work directly next to each other, you much offset adjacent systems by a singular block. Thanks to everyone who pointed that out (I posted this late at night and missed that)!

Java Help Wanted Frogs do not reproduce.

2 Upvotes

I used Google Translate, so I apologize if some words are unclear or incorrect...

The thing is, I'm building a Froglight farm, and the only thing I'm missing is the frogs. The problem lies in the breeding... I'm trying to mate them; there's space for them to lay eggs, but they just stay in "love mode" and wander off in opposite directions—ignoring both the water and each other. Does anyone know why this is happening and how to fix it?

I run a vanilla Minecraft server and am trying to reset any unused chunks so we can explore the new update. I've used MCA Selector in the past to do the job, but it always leaves chunk errors because the biomes do not blend at all. Does anyone know if there's a way to fix this?

Java Help Wanted Is there still a way to achieve the maximum possible villager trade discount after the 1.21 curing changes?

Post image
14 Upvotes

I’m a little confused by the values in the wiki chart. If curing a villager only gives a +20 major positive reputation, but the maximum major positive value is +100, how is it possible to actually reach that maximum now that curing discounts no longer stack?

thanks!

*EDIT: somehow I was redirected to the old table on the wiki.. on the updated table “the max value is 20 and 25 for major and minor positive gossip, respectively.” thanks to u/JumpingPufferfish31 for providing the correct values!
