Minecraft version: 1.18.1
Modloader: Fabric
Fabric loader version: 0.13.3
Environment: Multiplayer

Mod name: Just Mob Heads (Fabric)
Mod version: justmobheads-fabric_1.18.x-5.2.jar

As the title says, no mob heads from 1.16+ are appearing in the game or in the config when I looked for them. This includes the axolotls, goat, piglins, Hoglin, glow squid, and strider. The mod page says they should be in but they don't appear in the files.

Thanks for letting me know and giving the mod a try! The latest version of Just Mob Heads has this issue fixed.
