Was playing Just Cause & after liberating about 5+ places, the game froze up. Despite getting the achievement for it, what I got wasn't the last of the achievements for liberating all of these little islands. So hopefully this message goes out to anyone playing this fun game, just save it as there are times when you just have to remember to save or face the consequences.

Hopefully the sequel will let you save anywhere as long as you aren't on a mission (or it auto saves the fact you liberated an area), that and you can encourage others in your vehicle to join you in the stunt positions of hanging off the tail of a helicopter flying into a mountain.
