@SeaTurtle: This was discussed in another thread as well.
"Perfect" games in the sense of not having any inaccuracies, mistakes, or blunders flagged are not necessarily actually perfect.
Why? The threshold here for Stockfish to comment on a move is 0.5 pawns. Otherwise there would be comments on almost every move.
So yes, it is not so hard to imagine losing without any mistakes being more than half a pawn. If you just make a 0.4 mistake every move for 30 moves, you'll be -12, but the game would be "perfect".
It's not that this stockfish is too weak to notice those mistakes. It does, but comments are only shown for the mistakes that are >0.5.
Hope that clears some of that up :)
