Hello Michael,
i think in version B4.0 on page 89 this line is not correct:
this.players.value = playersForNewGame
GameViewModel.players has no property value. May previously it had been a MutableLiveData.
I hope i am not annoying you be sent so many erratas in a row. I am working on it while reading the book. If i don’t send them at once i will forget about them.
Best regards
