Board Game Arena

Recently I played a Harmonies game with my friend, with the new expansion “Crescendo”. When we summed up our points, we were shocked to find that we had exactly the same score, and even exactly the same number of animals.However, my opponent had 3 whispers placed on the board while I had none. So, with the new rulebook not mentioning the tiebreaker rule, what should the result be?A tie (cause we had the same amount of animals, and regardless of the whispers)? Or my opponent won (by the way, to sum up the animals and the whispers, or first compare the animals, then the whispers)?
At the same time, the new rulebook doesn’t mention the rule about the solo mode, so I would like to ask by the way: in solo mode, what’s the scoring rule of the “sun” for the board C or board D? And what about using the whispers, or the sanctuaries? Thank you!
