I played a game recently where the AI recommended move is shown to be one of the 6 biggest blunders at the end of the game. This has happened to me before on a handful of occasions. The move is a 20 point loss, and a 59% reduction in probability to win. Two other suggested moves are shown on the board, each one has both a lower point loss and a lower loss in chance to win.
Is the suggested move a bug, or does the AI factor other things besides change in score and chance to win?
I also suggest preventing the 6 biggest mistakes at the end of the game from including the recommended AI move.
Move 15, game in question: numbat vs. PRHG
