Pokey

Seems fixed with the new item pick up behaviour, cant reproduce it anymore, nice!

I can't reproduce this.

@smaugthegreat108 Minecraft 1.8 change how minecraft generates chunks, so all worlds behind that if upgraded will change biomes and generate ugly borders. Your comment has nothing to do with this bug.

Now im able to reproduce this bug.

If it's not im going to talk again with a friend, he is the one that should report it.

I think is already reported, but in my opinion Mojang could check what happened in 1.16.2 pr2, because something has changed in that version.

Well, it worked perfectly in 1.15.2, 1.16, 1.16.1 and 1.16.2 pre-release 1. Every version after that stopped working (pr 2, 3 and rc1)

If it worked and now it doesn't without upgrading Java, only changing the Minecraft version, I'm gonna say is Minecraft problem.

You are right Marcono1234, only happens when Item A has no damage/enchants and item B has enchants and damage.
This does not happen in 1.15.2, only in 1.16+

Zombified Piglins that have CanPickUpLoot enable, can pick swords that are worse than their current ones, making them take swords infinitely.
That means that the 5 minutes counter to despawn can reset because they are on the ground for less than 2 seconds, u can crash a world or a server in a few hours.
More zombified Piglings dying, more swords on the ground, more noticeable this bug is.
Easy way to replicate this bug is with any gold farm that dont pick up swords.

If you dont have a system to take care of the swords, they are gonna be thousands, more zombified piglins dying in a single spot, more swords in that spot and everytime that a zombified piglin enter that spot is gonna take all at one, thats gonna happen over and over again.

3 Years playing on my world, 1 month following this bug and scared, and yes, it happened to me now, 3 of my villagers just dissapear, non of them were at the chunk border, no zombies near and they had roof. All librarians with different levels. 1.15.2 vanilla.

Because is resolved. If you upgraded your world to a snapshot without a backup, then is your responsibility. Just clarifying, is resolved because if you upgrade a 1.15.2 world to the snapshot fix or newer, everything works as normal.

I tested this yesterday with my world (1.15.2, its was a backup) and everything worked fine (guardians, pillagers, nether fortress and witch huts), i have images of that, should i upload it?

Andy Huang, Elder Guardians dont "spawn" like guardians, they are created with the Ocean monument, like witches or shulkers, that has nothing to do with this.

The first reason they should spawn inside of wither roses is because they dont get dmg, just like other mobs spawning inside of other type of flower (like poppys), so why they shouldnt?
And second reason is like pigmans, they can spawn on top of magma blocks, because they are fire resistant, just like the wither skeleton is immune to the wither effect, so he should be able to spawn inside of it.
 

1. Not only having a wither rose farm is quite difficult, but a spawnproof area of 8 chunks on every direction is a high level work, I digged/tnt out a whole 21x21 chunks area, breaking this kind of thinks that only crazy or high level players do is rly annoying and sad. Hope this get fixed, if not I'll be completely out of this version (redstone and wither out, this is not for me).

2. Keep up the good work Mojang and I hope all of the people reading this are okay on this hard times ^^

I tried, i lost.

You actually cant remap your keyboard with Logitech Software, you will need a third person software to do that...

So now im literally not playing my world in 1.14.4, is horrible (at least for me) to play with other configuration.
