Zombie Wave Cloning Script Issue?

So I have a script in workspace that will clone zombies to a certain point in wave increments (every wave spawns more zombies) the problem is when I tested this as soon as the zombies teleport they die, is there any suggestions on how to fix this. I use MoveTo:() for teleporting the zombies and then I teleport their model. If you have any suggestions please tell me. Here is the code: (random map basically picks a randomap to spawn which is done above this, it is not important but when teleporting them they must teleport to [randommap].ZombieSpawn1)

The variable zombie found in local zombieclone = zombie:clone() is game.Lighting.Zombie

repeat wait(10)
	local wavenum = script.Wave
	wavenum.Value = wavenum.Value +1
	topgui.Value = "Wave " ..wavenum.Value.. "!"
	local zoms = math.random(5,10)
	local zomsfinal = zoms*wavenum.Value
	for spawn1 = 0, zomsfinal do
		local zombieclone = zombie:clone()
		zombieclone.Parent = game.Workspace[randommap]
		zombieclone:MoveTo(game.Workspace[randommap].ZombieSpawn1.Position)
		print("zombiespawn1 spawned")
		wait(2)
	end
until gameover.Value == true

You need to use the MakeJoints method to well, make its joints! When cloning a model that contains parts within it, you need to bond all of its joints back together!

repeat wait(10)
    local wavenum = script.Wave
    wavenum.Value = wavenum.Value +1
    topgui.Value = "Wave " ..wavenum.Value.. "!"
    local zoms = math.random(5,10)
    local zomsfinal = zoms*wavenum.Value
    for spawn1 = 0, zomsfinal do
        local zombieclone = zombie:clone()
	zombieclone:MakeJoints()
        zombieclone.Parent = game.Workspace[randommap]
        zombieclone:MoveTo(game.Workspace[randommap].ZombieSpawn1.Position)
        print("zombiespawn1 spawned")
        wait(2)
    end
until gameover.Value == true
