I started playing Rage about a week ago. I have found that I have 17 glitched achievements. Arts and Crafts, Tinkerer, Passive Aggressive, Three Birds, One Bomb Car, Keep 'Em Coming, Mechanocide, Jetpacker, Silent But Deadly, Hat Trick, Decapathon, JACKPOT!, Just a Flesh Wound, Deliverance, Minigamer, Demolition Man, Roadkill, Bringin' Home the Bacon. I have done everything required for these achievements and they still will not unlock. Any info that could help me fix this problem would be much appreciated.
