I have already collected all skulls in campaing, but the last one (the one in the truth and reconciliation) I got in a friend’s Xbox (I used a pendrive to use my profile, he has no internet). I got the achievement, but I lost my pendrive. i got home and rescued my profile through Xbox LIVE. As I wasn’t connected to LIVE when I got the achievement, I had to get it again. But when I got to the place where the skull is, it was not there, but I have it unlocked. I can’t get this achievement. I already tried to delete the save from my console, to no avail. Please help me.
Whoa, what a freaky problem 0_0 I have no idea what to do.
