  • Steps to Reproduce: Ask zoi to move in (with whom been interacting as an adult for the entirety of time my zoi was an adult, and my zoi is about to turn middle aged), and see age bar of zoi who moved in at 0

I formed a romantic relationship with a zoi. Both the zoi I control and the NPC were adults throughout and it’s almost my zoi’s birthday to middle age. When the NPC moved in before the wedding, I checked their age and it was back to Day 0 of Adult (which of course doesn’t make sense, as they were adults for the entire time I was interacting with them previously). Now my og zoi is about to turn middle age, and she’s going to be married to someone just beginning the adult stage. It’s immersion breaking and makes me want to stop playing the game.

There’s a way to change the age phase of your Zoi, I had done it but I don’t remember all the steps, you should find it in the Guides section.
Oh, here it is, I had saved it:

  1. Enable cheats in the Psyguide, if you haven’t already.
  2. Frame the Zoi whose age you want to change. Move the camera closer to the Zoi or select the Zoi.
  3. Open the cheats console ctrl+shift+c
  4. Use the showZoiInfo true cheat to get the ID of the Zoi whose age you want to change. Write down the ID in a notepad or somewhere.
    You’ll need it again later.
  5. Use CustomZoi to enter the CAZ.
  6. Save the Zoi as a preset.
  7. Save the outfits you want as presets by going to their respective slots - daily, school, party, summer etc.
  8. Exit the CAZ to the game.
  9. Exit the game to the lobby. You can choose to save the game, it doesn’t matter.
  10. From the lobby, enter the CAZ.
  11. Apply the preset of the Zoi you just saved, whose age you want to change.
  12. Customize the Zoi’s age. For example from Senior to Young Adult. This is where the magic happens!
  13. You can also change gender preferences if you want.
  14. You can change the daily outfit to match the new age, to differentiate the Zoi from the previous older version of the saved Zoi.
  15. Save the Zoi as a preset. This step is important! (Save the entire Zoi as a preset, not just the face)
  16. Exit to the lobby.
  17. Return to the game.
  18. Use CustomZoi to modify your Zoi. The CAZ will open.
  19. Apply the new age preset you just saved. It will be the first in the list of Zoi presets. Also identified by the new age outfit you had applied to differentiate the ages of the same Zoi. (Otherwise the presets can look the same).
  20. Change the outfits you want by applying the outfit presets you previously saved.
  21. Save the Zoi as a preset.
  22. Complete to exit.
  23. Save the game in a new

Thank you! I used this as a temporary solution.

It kind of still resets whatever age you choose to day 0 so it still would be better to have actual continuity within the game. I hope someone from the technical team comes across this as it doesn’t seem too impossible of a fix.

I don’t know why they don’t give us a cheat to SET AN AGE to any zois.

Like I can think of 3 cheats :

AgeUP [ZOI ID] → Sets the currently played Zoi to the beginning of the next age group (no effect on seniors)
AgeDOWN [ZOI ID] → Sets the currently played Zoi to the beginning of the previous age group (no effect on newborns).
SetZoiAge [ZOI ID] [Age] → Sets the currently played Zoi to a specified age from 1 to X
(depending on your game’s age settings, 100 is not the only maximum. Could be lower or higher.)

These cheats would also IMMEDIATELY change the size of the zoi to reflect its new age group if it changes as a result. They would resume aging normally from where they find themselves now, assuming aging is enabled.

I suggested this a very long time ago and it should not be hard to implement.
But yeah the work-around is possible but you can’t be precise with that, it’s at least something.
