Latest version of EMF and Fresh Animations, and 1.21.9 Minecraft.

• Bats are huge, not much to say about it;
• Baby cow, hoglin, zombie hoglin, horse, llamas, goats, cats, chicken, donkey, pigs, piglin, mooshroom, mule, ocelot, sheep, skel horse, zombie horse, turtle, dog (wolf), zombie, husk, drowned, zombie piglin are just cursed;
• Drowned, husk, zombie, piglin, piglin brute, skeletons, strays, wither skeletons, zombie villager, zombie piglin heads are wrong placed;
• Armors on piglins (and pumpkin on snow golems) are bugged (idk if it is like this on zombies and other entities)

This is not at emf issue, 1.21.9 changed how resourcepacks declare their compatible versions. Because fresh animations uses this to have internal pack overlays to fix bugs like old pre 1.21.2 baby models or old bat models, those old bugs models return because the pack doesn't know too disable / patch them.

On my discord update announcement I linked some files to temporarily fix fresh animations until fresh does it himself
