I mentioned in my other bug thread that after making my first report since the introduction of MT3, my notifications seem to have stopped refreshing--ie, when I get a new notification, it stays at the figure 23 that it had been at before that.
Furthermore, since the same incident, I haven't been receiving credits. I've been posting, have received two gallery comments and two favorites, and generally being active, and I haven't received any credits in the past couple of hours or so.
I don't know if any of these events are at all connected, though.
