Moving Sprite to nearest spawning object

Question

So for Unity I am trying to have a sprite in a scene move/teleport to the nearest spawning object to destroy it. What's supposed to happen is the teleportation and the destruction of the object but the sprite freezes after since I'm not done with everything.

Here's the class responsible for that
using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

/// <summary>
/// A collecting game object
/// </summary>
public class Collector : MonoBehaviour
{
    #region Fields

    // targeting support
    SortedList<Target> targets = new SortedList<Target>();
    Target targetPickup = null;

    // movement support
    const float BaseImpulseForceMagnitude = 2.0f;
    const float ImpulseForceIncrement = 0.3f;

    // saved for efficiency
    Rigidbody2D rb2d;


    #endregion

    #region Methods

    /// <summary>
    /// Use this for initialization
    /// </summary>
    void Start()
    {
        // center collector in screen
        Vector3 position = transform.position;
        position.x = 0;
        position.y = 0;
        position.z = 0;
        transform.position = position;

        // save reference for efficiency
        rb2d = GetComponent<Rigidbody2D>();

        // add as listener for pickup spawned event
        EventManager.AddListener(DelegateMethod);

    }

    private void DelegateMethod(GameObject arg0)
    {
        print("Pickup Spawned");
    }







    /// <summary>
    /// Called when another object is within a trigger collider
    /// attached to this object
    /// </summary>
    /// <param name="other"></param>
    void OnTriggerStay2D(Collider2D other)
    {
        // only respond if the collision is with the target pickup
        if (other.gameObject == targetPickup.GameObject)
        {
            // remove collected pickup from list of targets and game


            // go to next target if there is one

        }
    }


    /// <summary>
    /// Sets the target pickup to the provided pickup
    /// </summary>
    /// <param name="pickup">Pickup.</param>

    void SetTarget(GameObject pickup)
    {
        targetPickup = pickup;
        GoToTargetPickup();
    }

    /// <summary>
    /// Starts the teddy bear moving toward the target pickup
    /// </summary>
    void GoToTargetPickup()
    {
        // calculate direction to target pickup and start moving toward it
        Vector2 direction = new Vector2(
            targetPickup.transform.position.x - transform.position.x,
            targetPickup.transform.position.y - transform.position.y);
        direction.Normalize();
        rb2d.velocity = Vector2.zero;
        rb2d.AddForce(direction * BaseImpulseForceMagnitude, 
            ForceMode2D.Impulse);
    }


    #endregion
}

However my sprite is just stationary and sits there while the in-game objects spawn
