photonView.viewID Issue

Probably another basic silly thing that I'm just missing. I'm writing some code where a player fires a laser and that laser is destroyed when it A. hits another player, and B. hits a planet.

The players and the lasers have photonView's attached.

I call an RPC that says shoot me a laser. Code looks like this:

if(Input.GetButtonDown("Fire1")){
				photonView.RPC("FireLaser", PhotonTargets.All);
			}

[RPC]
	void FireLaser(){
		if(photonView.isMine){
			GameObject laser = PhotonNetwork.Instantiate("laser", 
			                                             new Vector3(transform.localPosition.x, 
			            transform.localPosition.y, 0) + (transform.up * 3f),
			                                             transform.rotation, 0);
			
			laser.GetComponent<Laser>().playerWhoShotMe = photonView.viewID;
		}
	}

where Laser().playerWhoShotMe is an public integer.

In the Laser script I have this code which, on collision with a planet, destroys the laser and let's me know which player's photonview.viewID the laser has on impact:

void OnCollisionEnter2D(Collision2D collider){
		if(collider.gameObject.tag == "planet") {
			Debug.Log(playerWhoShotMe);
			PhotonNetwork.Destroy(gameObject);
		}
	}

Everything works fine when I just have one player. However, when I bring 2+ players into the game. The photonview.viewID shows as '0' and I get this error thrown:

Failed to 'network-remove' GameObject. Client is neither owner nor masterClient taking over for owner who left: View (0)1009 on laser(Clone)

Plus some other gobbildy gook I can post if you want me to.

Of course this effects my player hit detection in the same manner, and I can't register the kills/deaths like I want to.

I know I'm misunderstanding a basic thing about how photonview's are owned, created and destroyed, but I don't know what it is.

This is really slowing me down, so any help would be appreciated. Thanks!
