player.CharacterAppearanceLoaded does not fire on clients. To my knowledge it should be. I was going to file a bug report, but I was not sure if this was expected behaviour, even if it doesn't make sense.

If someone would be able to confirm whether these is intentional and whether I am the only one experiencing this it would be helpful.

Client code

local Players = game:GetService("Players")

local localPlayer = Players.LocalPlayer

localPlayer.CharacterAppearanceLoaded:Connect(function(character)
    print("Appearance on client has loaded!")
    
end)


localPlayer.CharacterAdded:Connect(function(character)
    print("Character on client has been added!")
    
end)


wait(4)
local character = localPlayer.Character
character.Humanoid.Health = 0
print("Humanoid health is 0")

Server code

local Players = game:GetService("Players")

Players.PlayerAdded:Connect(function(player)
    print("Player added!")
    
    player.CharacterAdded:Connect(function(character)
        print("Character added on server!")
        
    end)
    
    player.CharacterAppearanceLoaded:Connect(function(character)
        print("Character appearance loaded on server!")
        
    end)
    
end)
