Whenever the bird eats the frog and the game restarts, an error pops up saying that the object was destroyed.

using UnityEngine;
using System.Collections;

public class Brick : MonoBehaviour {
    public int maxHits;
    public int timesHit;
    private LevelManager levelManager;
    // Use this for initialization
    void Start () {
        timesHit = 0;
        levelManager = GameObject.FindObjectOfType<LevelManager> ();
    }

    // Update is called once per frame
    void Update () {

    }
    void OnCollisionEnter2D(Collision2D col){
        timesHit++;
        if(timesHit >= maxHits){
        Destroy (gameObject);
        }
    }
    // TODO remove this method once we win
    void SimulateWin (){
        levelManager.LoadNextLevel ();
    }
}
