Prefab Instantiation Creating Object At Origin

I am trying to instantiate a gameobject I have at a certain posititon, and all my code is correct but when I run the game, it creates the gameObject at origin. Here is the code below, I do not want to hardcode the spawn point in because I want to eventually change it.

Main Controller

 void Start () {
         GameObject CircleTroop = GameObject.FindGameObjectWithTag ("Circle Infantry");
         Spawn spawnSystem = new Spawn();
         spawnSystem.createTroop (CircleTroop, true);
     }

Spawn Class

 public class Spawn : MonoBehaviour {
     private Vector3 playerSpawn;
     private Vector3 AISpawn;
     // Use this for initialization
     public void Start () {
         playerSpawn = GameObject.FindGameObjectWithTag ("Square Spawn").transform.position;
         AISpawn = GameObject.FindGameObjectWithTag ("Circle Spawn").transform.position;
         Debug.Log (AISpawn);
     }
     
     public void createTroop(GameObject troop, bool ai){
         GameObject TroopSpawn = troop;
         if (!ai) {
             Instantiate (TroopSpawn, playerSpawn, Quaternion.identity);
         } else {
             Instantiate (TroopSpawn, AISpawn, Quaternion.identity);
         }
     }
 }
