[FIXED] Sims age up/go back in age/days added/reduced

I just downloaded and installed today's update as well -- I haven't played at all since the last update. All of my saves are set to long lifespan. Immediately on loading into any household, age bars are filled and Sims age up. This has nothing to do with CAS -- it happens immediately when I load any household.

I'm really not sure if this is the bug that I am experiencing, but I still have wrong aging and sudden deaths after today's patch (on a backup save that was made a day before the first patch).

I'm on short lifespan and I noticed that one Sim who should have been on day 4/12 is now on 12/12 (and ages up) (4*3=12) and another that should have been on day 2/12 is now exactly in the middle of her bar (2*3=6=12/2). It's gives me the impression that their ages are all multiplied with 3 (which seems to be the new factor that normal lifespan is now longer that short lifespan).

same issue. I have had to turn off aging to stop all sims aging up in a household at the same time. all my sims lifespan bars are full since the bug of the previous update. after losing quite a few sims to sudden death of sudden aging up I turned aging off altogether. after today's update i decided to see if it was truly fixed. it's not. as soon as i turned aging back on (yes i typically use long lifespan) and went into a household they all aged up at the same exact moment when they were nowhere near ready to age up prior to the update that broke the game. testing a theory the only way to possibly resolve this, but I can't verify this yet, is to revert all your sims back in CAS before you load their households. So if they are adult and will instantly become an elder, for example, when you load them, go into CAS and change them to young adult and back to adult...this will essentially start their lifespan over again as an adult. I noticed when I did this to my test household their lifespan bars were not full anymore, but I can't verify this works because I would need to restart my game to test it and I have not done so yet. 

I took out all mods (never used MCCC), deleted caches and repaired the game. Ages are still wrong and cause sudden age ups and deaths (short lifespan).

Edit: The title of this bug has been adjusted, so I'm not sure if my problem is the same bug or something different (or another symptom of all the aging mess).

Edit: I would still very much appreciate to have an official statement about the adjustments regarding the lifespans that have been made and a list of all life stage for all life spans.

Thank you for your help. I just sent the save.

Regarding your comment: I could only observe changed life stages for normal lifespan so far.

If any EA employee happens to read this: please provide an official statement to the community with all the (intentional) changes that have been made regarding the lifespans and why this has been made. This has huge impact on legacy gameplay!

Yes, thank you, I've seen this one, but regarding the impact of the change I'm rather imagining a blog post to clarify things...
