Classic Arena: lost more points than listed in battle log
This is the same story every time the Classic Arena closes it's ranking: a sudden drop in points, that is not documented in the battle log.
Today, I ended around 4:00 just barely in Silver I (1302 points). When I returned to my game at 11:00, I was down to 1201 points (Bronze IV), with the battle log showing 4 defeats. If I am correct, with a loss you can loose at most 11 points, surely not 25.
Do others have the same experience? Can someone explain this to me?
