I am on Wednesday of the 15th week of my save. I got the 'just getting started' achievement (playing for 4 hours) again. Earlier today, I received the achievements that a sim had maxed handiness and that a sim had stayed awake for 24 hours (or maybe had done nothing social for 24 hours). The other is always one of the first I unlock, and there is no way I could go over 15 weeks in game without doing it if I tried. I have 2 sims in this household that have maxed handiness, and neither did it today. Discover 10 aliens is now locked, with progress 2/10. There are 3 aliens IN THE HOUSEHOLD. I've been doing save-as all throughout this save, because I'm playing the new career from dream home decorator and it's very buggy.
Update: I did a folder refresh and repaired my game. Even if I go back to my oldest version of this save file, the achievements are reset. It still says that 2 aliens have been discovered with 3 (undisguised) aliens in the household. My sims met 10 aliens before any of these aliens were conceived.
