There are a few games I've been playing where I have not been properly credited my achievements. Such as Assassin's Creed Brotherhood
(Collect All Feathers.)
Flying like an Eagle
(Jumpinmg with the parachute off the top of Castel Sant'Angelo)
(Throw a Long Weapon, Heavy Weapon, and a Smoke bomb more than 10m at a guard.
However I am sure there are other achievements I and other people have completed and have not been credited, When will this glitch get fixed?
