Re: Sim De-Aged

Thank you, I followed the steps and the issue is still present so I didn't make it to re-adding my Mods. The sim still cannot age up via cake, I tested to make sure another sim could and they can. 

@lisastar08 Can you please try (with the Mods/CC still not in the game):

1. Reset the sim  
2. If the issue remains please save the sim to the library (this may also reset them) then place the sim into another home and see if you can age them up via cake. If this works and fixes the sim you could delete the other sim (in the household you've been playing) and move this fixed sim into that household. You would have to cheat-create the relationships, career and money your sim currently has, though.
3. Or... you could try to save a copy of this sim with the entire household into the library, then place them again or in a new game save. The only relationships that will be preserved in this case will be the relationships with the sims saved with them into the library.

Let me know if this helps. If it fixes the issue you can then try re-adding your Mods/CC.

Edit... @EuphorialQueen just mentioned something I thought I'd add... If your sim is pregnant aging does not work while pregnant. Is your sim pregnant?

I did the sim reset and the issue persisted, so I split the sim from the household, put them in the library and moved them into another household, they still cannot age up via cake. They also still had their memories and relationships in tact. 

The sim is also not pregnant. 

@lisastar08 Thank you for letting us know.

Can you please try placing them from the library into another game-save (with no Mods/CC) and see if you are then able to age them up? Thanks!

Do you mean another played household? Just tried that and it didn't work. This is all being done with no mods/cc.

I also noticed in playing a bit tonight that the sim goes from 21 days now to 20, 19, then went back to 21 and hasn't moved again for days. 

@lisastar08 Thank you for the information.

What I mean is saving the sim into your library per the instructions in my other comment (there are links in the blue text to directions), then using the directions for making a new game-save in that comment (also see the link), then entering the new game save and downloading your sim into a home in that game save and seeing if you can age her up there.

If it works you could try re-uploading her to your library from the game save (the aged up sim), then enter your current game and re-place the sim in the household and see if she then functions/ages properly for you.

I managed to save her into my library and tested out going into a game save, that didn't work. I also created a new game, moved her into a household and tried there and that didn't work either. No mods or CC has been moved back yet. 

@lisastar08 Would you be willing to share this sim to the gallery and to add the household name here (maybe call it something like 'de'aging sim problem') and I could try it in my game?

@lisastar08  Is this a sim you created yourself, or one of the premades?  If premade, what's the name of the sim?

She's in the gallery under De-Age Sim Issue, thanks!

She's a pre-made, her name is Alex, but not sure her original last name, she married my sim. She has no family tree either.

@lisastar08 Thank you for uploading Alex. I have been chatting with @EuphorialQueen & @CGrant56 and they both have some ideas on this that I think are very helpful (plus I'm not feeling well) so I am tagging them to see if they can add some light to this. I'm told that Alex Moyer is in the tutorial and is a Maxis sim that is set to never age and never die. EuphorialQueen has played her in the tutorial, and CGrant56 has played with MCCC. 

Edit: I did download your Alex and had a roommate bake a cake and add candles, and the other sim got the option to blow out candles, but Alex does not have that option. 

@lisastar08 

I took a look at your sim and the original from a new game as well.  In a nutshell, the aging problem is caused by Alex (Moyer is the original surname) being a special sim that is used in the tutorial.  She has the hidden trait:  trait_SpecialNPC_isFTUERoommate which adds Disable Aging and Disable Death to the sim.  That explains a lot about why she has aging issues as the game wants to keep her a YA with a set number of days in her age group.  Probably so that she will be there if players rerun the tutorial.  It's a guess though.

I did some further testing and like @SheriGR neither the original from my test game nor your Alex get the Blow out the Candles option on a cake to age them up.  But I also went into CAS and created a clone of her.  Actually, I used add a new sim through Play with Genetics and created a twin for both the original from my game and your Alex.  The twin is not exact as it had different clothes and hair and her size was a little different but those are easy to change.  If you use the cas.fulleditmode cheat before you take the household in CAS, you can also deal with the size difference by using the sliders.

MCCC does not have a way to edit the hidden traits, only the original 3 that the player can assign at sim creation.  In fact, MCCC does not even see them.  I use a mod called ShowSimInfo by Itasan2 which you can find at MTS to see hidden traits.  That mod can't change anything.  It just shows all kinds of nice to know info about a sim.  It's a nice complement to MCCC.

But in the end, your situation comes down to the Alex sim in your game.  The only way I can think of to fix the problem is to clone her by creating a twin in CAS and then manually copying her clothes, hair, makeup etc. there. (You can also use MCCC to copy all the appearance things but I haven't tried doing that so I don't know how it works.  I just mention it so you know the option exists)  If you have the cas.fulleditmode active at the time you create the twin, you can also address her body size and traits.  Then delete your Alex and rename the twin.  Then you can use MCCC to set the skills to what your Alex had and if necessary, set any relationships that you couldn't in CAS.  MCCC will also let you change days in an age range and other things to get the new sim as close to the old one as you can.

So If you choose to go that way, I suggest you make notes if you want to duplicate the sim to get the new one as close as possible to the old one since there's a lot of things that will need to be changed.

Anyway, I hope this helps you.  

@CGrant56 Thank you for all of the awesome and helpful information!!

@lisastar08 After sleeping on this I won't know what I was thinking to not also mention that since we now have confirmation the this is a 'special' sim and is forcing itself back to the age it was designed to be... I suppose that another option could be to go CAS and edit the physical traits of your Alex so that she looks older, even though she is not. Add wrinkles, grey or semi-grey hair, whatever will make her look the age you want her.

An example of doing this is Vlad, from the Vampires pack. If you look at the screenshot below he obviously looks like an elder, but if you look at the sim age area at the top left he is actually a young adult:

@lisastar08 

@EuphorialQueen Just pointed out a method she used to age Alex so I thought I'd share it here. You would have to see if the age sticks, but it's another option:

1. Have Alex or a roommate make a cake and put candles on it. Immediately save and exit. 
2. Now Enter the lot with another sim. Have that sim click on the cake. scroll through all options until you find 'Age Up Sim'.
   
3. Click 'Age Up Sim' and you should see Alex in choices. Pick her to age up.
   
4. She should then go to the cake and blow out the candles. 
   
5. If you then enter CAS with Alex you will see she is one age group older.
   

Thank you all for your help, I'd never heard of sims like this before, and definitely makes my gameplay a challenge since she was already younger than her son and outlive her family that she had after marrying my sim.

I was able to age her to an elder via the cake trick it worked perfectly, thank you so much!!

Will I still be able to kill her via drowning or fire when I'm ready? 

@lisastar08 Glad that @EuphorialQueen's workaround worked. No, I would say she cannot die given what @CGrant56 had said about her hidden trait of not dying.

Oh no, cause now she's going to out live her son, grand children and so forth and mess up my family tree 😞

@lisastar08 You could follow @CGrant56's directions (comment #15) and make a twin of the sim, etc. and use that sim instead.

would that replace who the mom and grandma is of my other sims in the family tree?

@lisastar08 

Yes it will in a way.  Deleting a sim leaves all the portraits in the family tree where she was shown blank.  But you can fix that.  It takes some time and has be done carefully but since you use MCCC, it can be done with the Relationships option.  You can reestablish all the main relationships - wife, husband, mother, father, daughter, son.  

If all the relatives are still in the same household, it's pretty easy as all the sims you need to connect to are in one place and the new sim will have met them automatically.  But all it takes to do it for relatives outside the household is traveling to their household.  The key thing is that you need to meet them and get them into the replacement's relationship panel.  Click on the replacement to get to MCCC and click the relationship option.  Then work from the top down along the family tree so to speak.  Husband first, then children.  If there are grand children, those should self correct once you reestablish the relationship with the children.  

I've used it quite a bit when I last started a new save and brought sims into it from an earlier or another save.  Every once in a while, I do have a problem with getting a relationship to reset but eventually it will if you keep trying though.  Sometimes you have to save and exit, delete the localthumbcache file and try again.  

If you have never used the option and/or feel uncomfortable about doing this, make a copy of the save and put it somewhere safe before you start.  Once you've tried it and see what happens, then restore the save and go for it.  Actually, you should make a copy before doing anything like this just so you can recover if you need too.  

If you need any additional help, just ask.  Hope this helps.

Thank you!! This has all been really helpful 🙂

@lisastar08 Thank you for letting us know!! Happy simming! 🙌
