A while back I played Spartan Assault on the Xbox 360 and got all of the achievements. Recently I played through Spartan Assault on Windows and it transferred over certain stats, achievements, etc. I played through the whole campaign again as it has been a while and I unlocked every achievement except for the 'Extra Credit' and 'A for Effort' which pertain to the mission-specific Assault Ops. When I go to my Assault Ops however it says I have completed 90/90. (which transferred from my Xbox 360 data) Not sure if it's glitched or if there's maybe something I'm missing...
