I also believe it resigned in a lost position. The mistake was S14. It should have played J12 or M12 instead, which should lead to a win.

Take the ko, ignore one threat, play M12, ignore a 2nd "free move", play L10 and take the L9 stones, finally respond to black's two free moves, and I believe bonobot was still clearly ahead. Dan-level players seemed to be of the same opinion. In any event, it was certainly playable, not the best time to resign.
