Level 50 achievement not unlocking?

I cant tell you how frustrating it is to be thoroughly enjoying a new game and working your * off to complete all the achievements just for the auto achievement of getting to a certain level completely fail to activate and now you get to look at your 99% grade for the 100% work you did.

please fix your game and fix my achievement.

Manually claiming the achievements worked for me on all my games.
