🧭 Other plugins

no additional plugins are installed. just core slimefun.

Can confirm the same. Tested on both 1.16.5 and 1.18.1 server with slightly different plugin configurations:

As a side note, i tested build #987 on the 1.18.1 server and the breeders worked just fine

After clearing the block data of my breeder and placing a new one it was working. however about an hour later, it wasn't. and I don't believe it would be biome related, as i enclosed all the machines into a biome, spawned cows, and in some parts of the biome it would breed, while others it wouldn't. So far I'm not able to get a consistent way to produce it, but it is still bugging on me. I can confirm that with Rosestacker, that Bunnky had on the server does stop the breeding

Change title to: Auto Breeder can't breed stacked mobs properly.

This is a compability issue with stack mob plugins
Tested stacker plugins:

• StackMob
• WildStacker
• RoseStacker

Variananora, in further testing I can no longer reproduce the issue without the mob stacking plugins. As far as I can tell it's working fine.

also please include a list of all plugins with /pl

I'm having this issue right now on these versions:

Have no mob stacking plugin, used to have StackMob but removed it a couple months ago. Don't know if Auto breeders were working before or in between that time because tbh it's not a commonly used machine. Any ideas / anyone else seeing this issue?

A video showing the issue would be great.

Can confirm on 1.18.1 using build 1005.

Here is a video.

It is worth mentioning that our organic food items use custom model data, as shown in the video.

I tested this with the Animal Growth Accelerator and experienced the same problem - the organic food is not recognized or consumed, and nothing happens.

please provide a /sf versions screenshot and /pl

did the breeder didnt consume the food?

When not using a custom model data, is it still a problem? otherwise this can be attributed to #3446
