Hi! I already fixed this bug for the next update. Basically, I was using a singleton for the GameManager but decided against it, and forgot to update the integration packages. In both of the scripts that give this error, simply declare at the top: Code (CSharp): GameManager gameManager; Then in the Start method: Code (CSharp): gameManager = GameObject.FindObjectOfType<GameManager>(); And then replace all the places where it says 'GameManager.Instance' with 'gameManager'. Hope that helps. Otherwise PM me and I will send through the updated integration packages.
