I was having the same issue and i thought it was just this achievement so i went ahead and continued with the game and just didn't customize the 25th weapon or whatever... So i went a little further and another achievement popped up and of course same error again.. I had to completely sign out and back in for any of my other game achievements to show back up... When i signed back in and started the game back up i was in the same place i left off BUT I HAD NO ACHIEVEMENT and i cant go back to the city to get it because i have went to far in the game!!!!
Has anyone figured out what's going on with this? or anyone know of any KNOWN patches that are coming to fix the save, error and achievement problems?
