Camera movement speeds up when restarting game using Application.LoadLevel?

Hello,

The below scenario only happens when I preview my game within Unity. If I publish the game it seems to work fine. Dont know why.

I have a camera that has a moving script on it. It works fine untill my scene is restarted using "Application.LoadLevel" via a play again button. My camera then speeds up significantly. How do I make sure my camera keeps the original speed?

Here is my moving script:

 public class Done_Mover : MonoBehaviour
 {
     public float speed = 7.75f;

 public float moveX = 0;
     public float moveY = 1;
     public float moveZ = 0;
  
     public Rigidbody currentVelocity;
     
     
     void Awake () {
         currentVelocity = GetComponent<Rigidbody>();
         speed = speed * Time.deltaTime;
     }
     
     void Start ()
     {
         currentVelocity.velocity = new Vector3(moveX * speed, moveY * speed, moveZ * speed); 
     }
 }

Thank You, Raymond
