Bug Object script won't update

I've commented out some code because it was making my enemy look at the player in 3d instead of 2d but it still does it for some reason. I have no build errors in the script but maybe I missed something.

Enemy script:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class Enemy : MonoBehaviour
6. {
7.     //Variables
8.     public float speed;
9.     public Transform target;
10.     public Rigidbody2D rb;
11.     public Rigidbody2D playerRb;
12.     public float minimumDistance;
13.     public PlayerMovement playerMoveScript;
14.  
15.     public float hp = 1;
16.  
17.     public Transform firePoint;
18.     public GameObject bulletPrefab;
19.  
20.     public float bulletForce = 20f;
21.     private bool fireDelay = false;
22.  
23.     public void TakeDamage(float damageAmount)
24.     {
25.         hp -= damageAmount;
26.     }
27.  
28.     private void Update()
29.     {
30.         //Enemy death
31.         if (hp <= 0)
32.         {
33.             playerMoveScript.score++;
34.             Destroy(gameObject);
35.         }
36.  
37.         //Look at player
38.         transform.LookAt(target);
39.  
40.         //Get distance from player
41.         //var distance = Vector2.Distance (transform.position, player.transform.position);
42.  
43.         //If distance between enemy and the target is greater than minimumDistance move towards target
44.         if (Vector2.Distance(transform.position, target.position) > minimumDistance)
45.         {
46.             transform.position = Vector2.MoveTowards(transform.position, target.position, speed * Time.deltaTime);
47.         }
48.         else if(fireDelay == false)
49.         {
50.             Shoot();
51.             fireDelay = true; //Set delay
52.  
53.             StartCoroutine(FireDelay()); //Start fire delay
54.         }
55.  
56.         //Attack range
57.         /*if (distance < 50f && fireDelay == 0)
58.         {
59.             Shoot();
60.             fireDelay = 300; //Reset delay
61.         }*/
62.     }
63.  
64.     private void FixedUpdate()
65.     {
66.         //Look towards player (currently looks at the player in 3d making it disapear).
67.         /*Vector2 lookDir = playerRb.position - rb.position;
68.         float angle = Mathf.Atan2(lookDir.y, lookDir.x) * Mathf.Rad2Deg;
69.         rb.rotation = angle;*/
70.     }
71.  
72.     void Shoot()
73.     {
74.         GameObject bullet = Instantiate(bulletPrefab, firePoint.position, firePoint.rotation);
75.         Rigidbody2D rb = bullet.GetComponent<Rigidbody2D>();
76.         rb.AddForce(firePoint.up * bulletForce, ForceMode2D.Impulse);
77.     }
78.  
79.     public IEnumerator FireDelay()
80.     {
81.         yield return new WaitForSeconds(1); //Delay for set wait time
82.  
83.         fireDelay = false;
84.     }
85. }

 

Nm I fixed it by deleting it and adding it back into the scene.
