so recently i played survival with a bunch of mods in Java forge 1.20.1, Alex's mobs mod being one of them. and I noticed that most of the animals do not spawn or VERY rare. It was alexsmobs-1.22.5 , to be exact. i tried two more versions, i thought its maybe some other mods being buggy. I deletted every mod from the folder, only alex's mobs and citadel were there. And i encountered the same problem there was strangely no animals. only animals i saw are the vanilla mobs, blue jay birds, and crocodilles, and afew others however in really small number. And i dont konw if its intential or a bug, please fix.

i have this same issue, i hope someone can help.

I have the same issue. Im only seeing rhinos, blue jays, and grizzly bears no matter how much I search. If i go into creative all the eggs work properly just not naturally spawning.

i'm having the same issue and to the time im writing this, im trying to found what the hell is happening.

one alternative that im using is to use amber monoliths (which are from another mod called alex caves) to spawn the mobs naturally. it worked on a server i've played with my friends but im not 100% sure if this will work with all the ocassions.

how did you use that?

how did you use that?

basically just keep placing and breaking until the mob you want to "reahibate" appear inside the monolith. And just to remember that this block is from another mod so it might appear mobs from another mods as well

edit: Ok we have a problem. I discovered that the mobs are not spawning not because they acidentally got excessively rare, its because the natural spawn are not working at all. I tried messing with the config and tested on the fly (the most common to spawn) and even with high numbers of spawn weight, it didnt spawn once.

Which means that if the most common mob is not spawning its because it is pratically impossible that he can spawn naturally,
so it does to all the other mobs with unworking natural spawning.

This is way more serious than just a spawn issue, its broken.

Ok i found an solution.

These recent days i was playing on my friends maps (we use essentials for map joining) and the mobs was spawning in his map just fine?, so i got the conclusion that this bug happens because of the launcher. What exactly happened?, idk, but i decided to completely reinstall minecraft and..IT WORKED. its a bit frustating putting my options back but im just so happy that it actually worked.

i hope i could help you guys with this same issue :), sad that this is probably the only solution for now...
