I’ve completed the main story and rescued the sheriff etc, yet the achievement for rescuing the sheriff hasn’t unlocked, also, the “explosive surprise” achievement is frozen on 80%, no matter how many enemies I kill with sabotaged vehicles, it won’t go up to 100%, I’ve even started a new game as they are the only 2 achievements I have left to get (apart from the arcade ones) yet it’s still stuck at 80%.
HELP
