Lives persist, score does not, can't figure this out

I think its the case that @Brian_Trotter described to me a couple of days ago in this topic:

Null Reference Exeption with Singletons (2d Pixel Combat)

Thanks for clarification and your rules - they are helpful to understand. Thanks to both of you I understand better how to use Awake and Start. I did check what precisely I got wrong, and it was calling internal function of my class in Awake instead of Start. This function was calling another function and that third function was referencing the Singleton. Well, quite convoluted… Now, I guess I will remember not to call anything on Awake, unless it is base.Awake()
