Basically, Animals such as cows and sheep don't spawn in the plains biomes, only horses spawn in the plains biome for some reason. I was only able to find cows and sheep in biomes like the savannah, but nowhere else. there were also no axolotls in the underground (Or Anywhere) to be found. I don't know if this is a new game feature or a bug that's causing this, either way, it's kinda getting on my nerves. please help!!!

What I expected to happen was...:
Animals start spawning in the usual locations when I restarted the game or recreated the world

What actually happened was...:
Animals still didn't spawn where I was expecting them to, and no axolotls were spawning wither

Steps to Reproduce:
1. recreated the world on the same seed and same game version
2. looked around for the missing animals 
3. could only find animals in the biomes where they didn't naturally spawn and didn't find axolotls anywhere underground
