I’ve been using the achievement unlocker. My profile hasn’t been synced with live.
I know it’s possible to recover my profile and start unlocking again, but is there a quicker solution to fix silly little errors? for example: i’ve accidentally unlocked achievements such as “completed 3rd mission” before i’ve actually unlocked “completed first mission” yep, derp. …is there a quick way to rectify this or is it simply a case of recovering profile?
