Re: Sims 4 PC Aging Glitch

Did you create the Sim yourself or is he an NPC?

There are some hidden traits that come with City Living, which can cause this issue. 

If you suspect this could be the case you can opt to download a mod called 'Sims Info' (can't link it as that is against the TOS).

With that you can check what hidden traits your Sim has. 

I have tried both. I have tried creating a Sim myself and tried using one of the default ones. Nothing works.

I do have City Living, but my friend and I use the same account. We both have no mods, and since we use the same account, we use the same expansion packs, and her game works just fine. I am starting to think that my laptop is causing said issue. However, I will not rule out the chance that it could come from City Living. 

Do you have the same issue with a new save file?
