Seems to be the bug again. See, no entry for Stack Apps for yesterday, just SO and MSE:
I have earned 20 reps on Stack Apps today. But I am not seeing notifications for up votes in the drop down, however I see the number (etc +10).
Even when I recently got 10 reps on Stack Apps, I saw +10, but they can't be seen anywhere in my drop down.
Halp? And yes, earlier (four days ago) everything worked fine.
