I hate to constantly make new topics here, but just now I played La lune du minuit eternel medium, FCed it for the first time, improved my score, but it didn't register at all.
It's not even in my latest plays.
None of my stats were changed from the play, so it seems like it hasn't been recorded at all.
I can also confirm that my internet was not down, I had people talking on msn while playing the song, and continued to talk afterwards.
I checked the connection, it hasn't restarted.
Now I'm not trying to get my score back, I'll probably FC it again later today, but I'm just trying to point out that this might be some kind of bug, maybe it's also connected to that other bug that was delaying score submissions.
