Picture Flaggers badge not being awarded

Picture Flaggers should be awarding at 10/50/100 flags. I kept track of recent flagging and know I have done at least 25, yet have not been awarded the badge.

A long-standing bug, has been previously reported at:

>1 lemontwist: Sorry for the trouble, let's keep the 2016 bug Nevov mentions open for this and bump it instead.
