Okay, so i first noticed this problem months ago, but injuring my knee, and issues with my computer kinda prevented me from trying to figure out what was happening. And both turned out to be long term issues...
Anyways, the problem is with slow aging. I had it in my game, and it worked fine. And one day, i hadn't added anything new to my game, it stopped working. Sims aged daily again.
I tried installing the new slow aging controller, but that didn't work either.
It had me totally puzzled. I was going to figure it out, but then all the other stuff got in the way. So i recently tried to figure out what might cause slow aging to stop working.
I added it as the only mod and it worked. I added all your mods i have, and it worked. I added inteen, and it stopped working.
Now i do remember i changed some of the flavor packs shortly before noticing the problem. I had no adult teens, and took that out and installed college admissions. So i thought i had found it. But changing the flavor packs around, doesn't change anything, and it's still not working.
This has me completely puzzled, as it did work together before. Not sure if i had changed anything else, as it was months ago, but i've tried adding and removing any of the flavor packs i might have altered. But whatever i do, slow aging isn't working.
Also, putting all mods in, and leaving only inteen out, has slow aging working. So the only conclusion for me is that inteen is somehow conflicting with slow aging. But why then did it work before?
Now my computer is going to have to go back to the store very soon, as the problems are getting worse, so i may not be able to try many other things. I thought you might want to know now i've figured this out so far though, even if i can't promiss i can help trying things.
