Not sure if this would be considered a bug or just an annoying quirk...

When advancing to the next level of espionage on a race, am I the only one who receives the progress report twice? I get a notice that I've achieved the next level of espionage. I click 'NEXT', the turn progresses, and then I get the achievement notice again. I guess it's not a big deal, but I just hate being told the same thing twice.
