Mob appears on the spot, but does not move

So, I have a basic system to spawn a mob at the desired point, but for some reason when he can appear it does not go, but for example, the other model (Zombie) is going. As I understand the problem is in the model itself. If anything, here are two scripts on spawning and movement. Also, screenshots of the situation, as well as a file and Zombie mobs:

local mob = require(script.Mob)
local map = workspace.map

for wave = 1, 5 do
	print("WAVE STARTING:", wave)
	
	if wave < 5 then
		--print("1")
		mob.Spawn("Zombie", 3 * wave, map)
		--print("2")
	elseif wave == 5 then
		mob.Spawn("Zombie", 100, map)
	end
	
	repeat
		task.wait(1)
	until #map.Mobs:GetChildren() == 0
	print("WAVE ENDED")
	task.wait(1)
end 
local ServerStorage = game:GetService("ServerStorage")
local mob = {}

function mob.Move(mob, map)
	local humanoid = mob:WaitForChild("Humanoid")
	local waypoints = map.Waypoints

	for waypoint = 1, #waypoints:GetChildren() do
		humanoid:MoveTo(waypoints:GetChildren()[waypoint].Position)
		humanoid.MoveToFinished:Wait()
	end
	mob:Destroy()
end

function mob.Spawn(name, quantity, map)
	local mobExists = ServerStorage.Mobs:FindFirstChild(name)
	
	if mobExists then
		for i = 1, quantity do
			task.wait(0.5)
			local newMob = mobExists:Clone()
			newMob.Parent = map.Mobs
			
			newMob:PivotTo(map.Path.Start.CFrame)
			

			coroutine.wrap(mob.Move)(newMob, map)
		end
		
	else
		warn("Requested mob does not exists:", name)
	end
end

return mob

Check if any of the parts in the Mob are anchored, this will prevent movement from happening.

I have already checked it, and all parts of the body unanchored, you can see for yourself)
