Achievement 'Getting the Hang of It' still bugged.

syain

I was under the impression it was going to be fixed along with 'Nerves of Steel' but apparently the issue is still in the game. Keep ranking up from rank 2 to 1 and I never get it. Do I need to get all the pips for a given rank or what?

EDIT: The issue has been fixed as of patch 4.7.1
