In the screenshot attached you can see the player named Gualdo04 was the first in reaching 15 points triggering the last round of the game. The game declares them the winner, without letting me make my last move. Otherwise, I would have bought the card in the bottom right corner and that would have let me total 15 points by getting the noble on the left. I would have won as I have less cards.
Am I missing something?
