Whoohoo! I never gave up hope but came close a few times. My Lone Wolf chevo unlocks! It took from 2/27/2016 to 5/11/2016 with no way of knowing which effort fixed it, because with the help of #xboxsupport, we tried everything…several times. I’m just very happy to have it and now my game shows 100% completion – the way it should. I love you #xboxsupport @XboxSupport
After doing everything xbox support asked me to do, myself and other gamers have still not received the chevo. I went to check on my console today and now it says 100% complete (instead of 93%) but the chevo is still locked. On all the forums i posted too there are more gamers asking for help but no fix reported.
