This is weird, won't give me the achievement "girl and a firefly" I've tried power cycling my x1 and everything still won't pop. And this is the only achievement I'm missing for 1000/1000 *frustrated grunt*
This was discussed at Xboxachievements, and it seems the only fix to unlock these achievements was to delete your save and start over again, they did try new game+ but that did not unlock those achievements either, the only way was to start over with a new file.
