[BY DESIGN] Age groups start with random days added from CAS/Gallery

@Nekoboy69 @Aoife516 What you guys are describing sounds like a bug, but I'm just not able to reproduce, I'm not seeing any close-to-full age bars. 

I started a New Game, created 4 Teens and 4 Adults in CAS, went into the Options to change the Sim Lifespan to Normal, then placed the household down onto the Sandtrap Flat in Oasis Springs. When I got into Live Mode every Sim's age bar was pretty low. The most full I saw was a teenager with 12 days remaining til age up. I've repeated this process a few times now and I always see the same.

I've also tried adding a new Sim to an existing household and leaving that household as unplayed. So like, I added an Adult to the Pancakes household, then went back to the household I was playing and had a Sim visit the Pancakes, and I'm not seeing the Adult immediately age up. 

I've also downloaded a random Teen from the Gallery, placed them on a random lot, and had one of my Sims go visit the Teen, and yeah he's not aging up.

Could the issue you're seeing possibly be related to Mods? If you move your entire Mods folder to your Desktop and restart your game, do you still see it occurring? Or how about if you move your entire TS4 folder? If that doesn't do the trick, could you possibly share a video or save file? Thanks for the help! https://answers.ea.com/t5/Bug-Reports/INFORMATION-How-to-Send-User-Files-to-The-Sims-4-Team/m-p/6065302

Edited to add: If you're able to reproduce this issue without mods, could you possibly file a new AHQ Report? Maybe something called "Sims age up immediately when coming out of CAS" or something like that. Thanks so much!
