After 3 weeks breaks I've played 4 matches (1 yesterday, 3 today). All of them won, but the problem is that on the profile page 2 first matches give me score (in "Result" column I see "Win (+30)"), but two latest - contains only "Win"?
Blizzard had said that they were turning off point increase/decrease because of instability with the servers. They don't want a bunch of people complaining because they lost points due to disconnects. The downtime was pretty short if I remember, which is why it probably only happened for a few games.
