Hi there! First question on the forums!
Im currently making a game in which waves of enemies are sent to the player.
My most recent enemy has a more complex AI script then all of my other enemies, which work completely fine when instantiated.
my Reaper enemy has 3 behaviors: chase, aim, charge.
When placed in the scene the 3 behaviors act normally, however when I instantiate Reapers, then seem to be stuck on the chase behavior
Any Help would be greatly appreciated! <3

private Color DefaultColour;
public SpriteRenderer sprite;
private void Start()
{
target = GameObject.FindGameObjectWithTag("Player");
DefaultColour = sprite.GetComponent<SpriteRenderer>().color;
StartCoroutine(Think());
}

{
}
//Deal damage to player
private void OnCollisionEnter2D(Collision2D collider)
{
if (collider.gameObject.CompareTag("Player") && collider.gameObject.name == "Player")
{
//Debug.Log(collider.transform.name);
Health enemy = collider.transform.GetComponent<Health>();
if (enemy != null)
{
enemy.TakeDamage(Damage);
}
}
