How Do I Stop Cloned AI From Losing Joints?

I am cloning zombies from a template zombie (held in the Lighting) for a game I am building. When the zombies are cloned, then teleported, the zombie spawns dead and in pieces! This is the teleport and spawn portion of the script:

wait(math.random (1, (8 * RoundNum.Value)))
            local Zombie = game.Lighting.TemplateZombie:Clone()
            Zombie.Name = " "
            Zombie.Enemy.MaxHealth = 100 * RoundNum.Value
            Zombie.Enemy.Health = Zombie.Enemy.MaxHealth
            local choices = game.Workspace.spawnPads:GetChildren()
            local teleportto = (choices[math.random(1,#choices)])
                if teleportto~=nil then
                    local torso = Zombie.Torso
                    local location = teleportto.Position

                    local x = location.x
                    local y = location.y
                    local z = location.z

                    x = x
                    z = z 
                    y = y 

                    local cf = torso.CFrame
                    local lx = 0
                    local ly = y
                    local lz = 0
                    torso.CFrame = CFrame.new(Vector3.new(x,y,z), Vector3.new(lx,ly,lz))
                    Zombie.Parent = game.Workspace

Note that the "joints" are snaps. I checked and the zombies max health is at 100 (what is should be) Joints are labeld Neck, Left Hip, Left Shoulder, Right Hip, and Right Shoulder. When copied template zombie comes out of the spawn pad, it only has it's Neck left.
