Friendly creatures are not spawning naturally in old chunks

Edit by @unknown:
It seems that friendly creatures like new wolf variants and armadillos don't spawn at all in old (upgraded) chunks, not even in new chunks, only once in newly generated chunks.

Steps to Reproduce by @unknown in this comment

  1. Create a single-biome savanna world in 1.20.4 with commands enabled

  2. Set simulation and render distance to 16 or more.

  3. Once you load in a world, fly around spawn to load new chunks.

  4. Upgrade it to 1.20.5

  5. Place 2 always active repeating command blocks with commands bellow

    /execute as @e[type=armadillo] run say MC-271088 is false
/execute as @e[type=armadillo] run effect give @s glowing infinite

  6. Run /tick sprint 2d and stay still.
    ❌ Armadillos don't spawn.

  7. Run /tick sprint stop otherwise chunks might not load

  8. Run /tp @s 30000 320 30000 

  9. Repeat the same steps in 5, 6 points.
    ✔ At least one armadillo shoud have spawned

  10. Wait until all chunks are loaded and run /kill @e[type=armadillo]
    ❌ New armadillos don't spawn.

Note by @unknown in this comment

I originally thought that this was intended behavior, and occurs because of something called a "mob cap", which prevents mobs from passively spawning after reaching a maximum capacity. For friendly creatures (which includes armadillos), this cap is only 10, and is likely already filled by existing mobs in the area like sheep, pigs, horses, etc. Therefore, no additional friendly creatures can spawn. On top of that, friendly creature spawns are also quite infrequent.

I ran steps 1 and 2 as instructed (in 1.20.6), and, sure enough, nothing spawned. However, I then ran /kill @e[type=!player] to kill all the mob-cap-filling mobs. I was expecting some creatures to spawn, maybe run the kill command a couple more times and wait until an armadillo spawns, putting this report to rest. However, I found that, despite waiting multiple in-game days, no friendly creatures spawned at all. It is possible that friendly creature spawns are just that rare, but I am highly doubtful of that. It is also possible that this is a savanna-specific issue, but I am not sure and do not have the time to test it right now, and I do not see any reason for that to be the case.

Old Description

With the Armadillo // Wolf Armor Update officially releasing yesterday, I assumed that I would be able see these little critters and new wolf variants on my Minecraft realm once it updated.

Unfortunately, that didn't happen. Despite traveling to the Savannah biome on my server, no Armadillos spawned. I tried downloading my realm to my Minecraft single player mode as an attempt to sync the update into my realm. Once that didn't work, I tried optimizing my world. Once that didn't work, I attempted to load back into Minecraft via the Installations menu and customizing a "most recent launch" through there. I tried loading back into my Realm World once more and.... nothing. No armadillos; no new wolf variants.

If you want to try this bug out for yourself, just try to find an armadillo on your realm in a pre-existing Savannah biome. They won't be there. And if they are, please let me know what I am doing wrong, because I have tried everything aside from deleting this world from my realm (which I would prefer not to do since I've had it for 2+ years now.

Thanks.

Hello, the realm is on 1.20.5 right?
If so, you should see Armadillos in the Badlands and Savannah regions.
Try finding some new chunks and let me know if you find any, this could also be an issue with the update being released for Java Realms.

Passive mobs newly spawn very rarely, if there are a lot of other passive mobs already in the area. Intended.

I am on 1.20.5. I loaded in new chunks which took a long time, because it was 10 thousand blocks away from the map chunks I had already filled out. I did not see any Armadillos in the Badlands, but I finally did see one in a Savannah biome.

However, this is frustrating, as I shouldn't have to load in new chunks of the realm in order to discover passive mobs that are supposed to regularly spawn in those biomes. It would be different if it was a new biome they spawned in, or if there was a new structure that needed to load in. When variant cats were first introduced in Minecraft, I didn't need to seek out a new village in a new chunk of world in order for them to start spawning. They just started spawning. Same for Phantoms, they just started spawning after being awake for three nights (I understand that Phantoms aren't tied to a biome, but it shows that Mojang has the technology to make Armadillos spawn in already loaded in chunks).

Also, while I understand that Passive Mobs don't spawn super frequently, my other world (in which I was testing the update on) had a bunch of Armadillos spawn naturally over time. So, I don't see as to why it should be any different now.

 

Thanks for trying to help. I appreciate it. I just hope they fix this spawning issue in a quick bug fix update or something.

Can confirm in singleplayer mode. It also seems like armadillos don't spawn at all, not even in the new chunks, only once in chunks that have been just generated.
