I think I found a nasty bug in the evaluation of matches that are set up for a fixed amount of games.
Here is a match that was for 5 games, and I won it 3:2: Fevga (Aganju vs. Doris)
However, the fifth/last game of the match went to my opponent (so I lead 3:1, and then it ended 3:2 - still a win for me).
The event message I got, however, declared that *I lost*, and deducted some points from my rating (and gave rating points to my opponent).

I would guess that the code uses the result from the last game for its decisions, as - typically - the winner of the last game is the winner of the match - but not for this type of match.

Did anybody experience this too?
