findgameobjectwithtag only working sometimes

Hello, for some reason it appears that findgameobjectwithtag does not work sometimes. I receive this error only sometimes:

NullReferenceException: Object reference not set to an instance of an object
Unity says the error is at line 5
Heres the code :

targets = GameObject.FindGameObjectsWithTag("Good"); //stores all viable targets
		for (int i = 0; i < targets.Length; i++) { //goes through targets
			GameObject target = targets *;*

  •  	if(target != null) {*

  •  		if(Physics2D.Raycast(transform.position + new Vector3(0, 0.6f, 0), target.transform.position - transform.position, range).collider.name == target.name) {*

  •  			Debug.DrawRay(transform.position + new Vector3(0, 0.6f, 0), target.transform.position - transform.position);*

  •  			float weight = Vector3.Distance (target.transform.position, transform.position);*

  •  			if (weight > highestWeight) { //chooses closest/most important target*

  •  				highestWeight = weight;*

  •  				bestMatch = target;*

  •  				lastTargetSeen = target;*

  •  			}*

  •  		}*

  •  	}*

  •  }*

Hello,

On line 5:

Physics2D.Raycast(transform.position + new Vector3(0, 0.6f, 0), target.transform.position - transform.position, range).collider

Nothing guarantee you that the raycast is currently hitting a collider.
