Unexpected symbol error ?

This has to be a bug... Unexpected symbol '}' on lines 18 and 21.

 using UnityEngine;
 using System.Collections;
 
 public class core : MonoBehaviour {
     
     public static float healthC;
     public Rigidbody rb;
     public float speed;
     
     void Start () {
         healthC = 100;
     }
     
     void Update () {
         if (healthC <= 0) {
             Destroy(gameObject);
         }
         if (Input.GetKey (KeyCode.W){
             rb.AddForce(Vector3.forward * speed * Time.deltaTime, ForceMode.Acceleration);
         }
         if (Input.GetKey (KeyCode.UpArrow){
             transform.Rotate(Vector3.up * speed * Time.deltaTime, Space.World);
         }
     }
