(ITween) Problem with Spawning Enemies

Questions & Answers
1

I’m making a bullet-hell like game and am having problems spawning enemies

So I have this EnemySpawn script which takes in a type of enemy and spawns it.

void Spawn()
{
GameObject newEnemy = (GameObject)Instantiate(Enemy);
}

Attached to the enemy is a WaypointMovement script which uses ITweens MoveTo function.
It compiles properly and all but Unity is giving me this a error (NullReferenceException: Object Reference not set to an instance of an object).
It happens on the LateUpdate and the TweenUpdate of ITween.

EDIT:
It happens on line 4624 and 6598 of iTween.cs (The first line of TweenUpdate() and LateUpdate() respectively)

Welp!

EDIT:

Well, my Enemy gameobject only has my WaypointMovement script attached to it.
Here is my WaypointMovement script.

using UnityEngine;
using System.Collections;

public class WaypointMovement : MonoBehaviour
{
    public Transform[] waypoints;
    public int rate = 20;
    private int currentWaypoint = 0;

void Start()
{
    MoveToWaypoint();
}

void MoveToWaypoint()
{
    //Get the time it takes to travel with the distance and rate
    float t = Vector3.Distance(transform.position, waypoints[currentWaypoint].position) / rate;

	//Get iTween to apply the movement to the object
    iTween.MoveTo(gameObject, iTween.Hash("position", waypoints[currentWaypoint], "time", t, "easetype", "linear", "oncomplete", "MoveToWaypoint", "Looktarget", waypoints[currentWaypoint].position, "looktime", .4));

    //Set the currentWaypoint to the next one
    currentWaypoint++;
	
	//Start from the first again
    if (currentWaypoint > waypoints.Length)
    {
        currentWaypoint = 0;
    }
}

}

EDIT:

This enemy has the WaypointMovement script attached to it.
The enemy works fine when I manually place them onto the scene.
However, it gives me a null reference error when I try to spawn a new enemy using the Spawn() in my EnemySpawn script.

EDIT:

This is what happens when I use my spawn function.

Change currentWaypoint > waypoints.Length to currentWaypoint >= waypoints.Length.

Or you can remove the conditional altogether and use currentWaypoint = currentWaypoint % waypoints.Length;
