I've a problem on my xbox one (I've tried to unlock achievments on my xbox 360 and it worked)
So the last three weeks I SHOULD HAVE unlocked three achievments from 2 different games (one achievment per week) and I didn't unlock them.
I'm absolutely sure that I should have unlocked them.
The games concerned are Ruse Sons of Rome and Call of duty ghosts.
Thank you for your help.
