Find File working in preview but not in game

So I have this file in my saves file, Another script deletes the file and replaces it with another when triggered causing another script to open a different scene, anyone got an idea?

	IEnumerator Start () {
		Start:


		if (System.IO.File.Exists ("Assets/Saves/original")) 
		{
			SceneManager.LoadScene (72);
		} 
		else
		{
			yield return new WaitForSeconds(2);
			goto Start;
		}

	}
}

So it loads scene 72 when I press the play button, but when I build and play the game it doesn’t work

Use Application.persistentDataPath for your saves
