Some know issues:
Running multiple instances of the game at the same time may give save incorrect values. I.e. if the player unlocked achievement 1 in one window and shortly after that unlocked achievement 2 in another, only the unlocking of achievement 2 will be registered.
If the achievement definition change, the save will forget unlocks that are no longer defined.
