NullReferenceException and m_InstanceID == 0 on LoadLevel (C#)

So I have a script that spawns in my player as soon as the level loads. It works perfectly fine when loading the scene straight-up.

However, when I load that scene from another scene using the LoadLevel function, I get these errors.

m_InstanceID == 0
UnityEngine.Object:Instantiate(Object, Vector3, Quaternion)
GameMaster:Start() (at Assets/Scripts/PlayerScripts/Character Classes/GameMaster.cs:12)

NullReferenceException
UnityEngine.GameObject.GetComponent[PlayerCharacter] () (at C:/BuildAgent/work/d63dfc6385190b60/artifacts/EditorGenerated/UnityEngineGameObject.cs:30)
GameMaster.Start () (at Assets/Scripts/PlayerScripts/Character Classes/GameMaster.cs:13)

Both of them link me to the same lines of code:

	public GameObject playerCharacter;

	private GameObject _pc;
	private PlayerCharacter _pcScript;


	void Start () {
		_pc = Instantiate (playerCharacter, Vector3.zero, Quaternion.identity) as GameObject;
		_pcScript = _pc.GetComponent<PlayerCharacter>();

		_pc.name = "pc";
	}

I’m at my wit’s end here. I’ve looked up other ways to fix the m_instanceID problem and none of them have worked.

And I fixed my own problem within minutes of asking the question.

For anyone who stumbles onto this with a similar problem, make CERTAIN your instantiated object when called from the previous scene DOES NOT have a “DontDestroyOnLoad” script.
