i wouldn't exactly say that the product isn't working. my second save game i have 91% finished.
i also backed up my save data in case i might lose it. but consider i have the steam version. i was also suggested to disable steam cloud. because it doesn't always sync. it seems more or less its a problem with GFWL rather than the game itself.
lets hope Rocksteady have learned there lesson next time. by not bringing it out on GFWL.
because even the achievements are broken. while steam achievements itself just shows them up perfectly fine.
this might also be the cause of fixing the game. i still believe its not entirely there fault to begin with. but constant delaying can annoying for people, who really wants to play it without any ground breaking bugs.
but consider i have allot of patient. you won't hear me complain any soon
