unity 5.3 InvalidOperationException

hi,
since i’ve upgraded to unity 5.3 i get this error:
InvalidOperationException: Operation is not valid due to the current state of the object
System.Collections.Generic.Stack`1[System.Boolean].Pop ()

in this case i was trying to attach the text in the hierarchy so that it could be displayed during the game.
i don’t know if it’s relevant, anyway here’s the script:

        public static int coins;
        public Text coinsText;
    void Update () {
    		Move();
    		Rotate ();
    		Shoot ();
    		UpdateText();
    	}
    
   void UpdateText() {
        		coinsText.text = "Coins: " + coins.ToString();
        	}

the scirpt is attached to the player, which is a prefab.
can you help me solve this? thank you in advance:)

Happens to me all the time, most likely a bug
