I'm already sure what the problem is and it's not a big deal but I'd like someone else to tell me what they think.

Name of app: Hitmaker
Cost: Free
# of achievements: 5

To start off, the 5th achievement doesn't show up in the list to begin with.
4 of 5 yet I only see 4. I'm guessing it's a hidden achievement. See for yourself


So here's the full list of achievements according to this site:
Game Center Achievements: Hitmaker: Achievement List

It looks like I'm missing "Early Bird - First person to promote a song"

Now it's funny because I've completed this at least 10 times and the achievement never shows. :(
Here's a picture of me completing the task on a random song I searched.


And I do it again...




So yes that is the problem with this game, I've contacted the devs but get no response as usual.

What do you guys think? Am I doing something wrong? lol
