I believe I've noticed an issue with the blunder count that gets displayed after a computer analysis. It appears that if a bad move would take someone from a numeric +/- (e.g. -1.54) to "mate in #" it does not get tallied.
An example of this can be seen in this game: http://en.lichess.org/5djO2l9G#0
12...e5?
is a blunder, but not included in the totals for inaccuracies/mistakes/blunders below, nor indicated as such in the annotation text following "(1.55->Mate in 3)" Maintaining consistency with other annotations, you'd expect to see "(1.55->Mate in 3) Blunder.".
