How can I make a player clone spawn properly?

Your character was loading in too quickly meaning that the clone would spawn before any of the textures had been fully loaded.

game.Players.PlayerAdded:Connect(function(plr)
    plr.CharacterAdded:Connect(function(char)
	char:WaitForChild("Shirt" and "Pants")
        char.Archivable = true
        local d = char:Clone()
        d.Parent = game.Workspace

        d.UpperTorso.CFrame = CFrame.new(0,50,0)

    end)
end)
