Hello, hope I'm posting in the right place!
I use TS2 aging and I would like my Sims to continue aging and normal passage of time while on vacation (World Adventures). Like if they leave Friday for a 3day trip have it actually be Monday when they return home, and each Sim is 3 days closer to the next Life Stage. Is it possible? I currently have MasterController and Overwatch.
Thanks!

Hi there. You are in the correct place. The mod that controls travel and manages multiple worlds within the same ongoing games is NRaas Traveler.

But I am afraid what you are asking for is not possible. The world traveled from when sims go on vacations is in a state of suspended animation while it is not being simulated. If it was Monday at 8 pm when your travel party left, it will be Monday at 8 pm (maybe 8:01) when they return and everyone should be doing exactly what they were when you left.

It may be possible using Traveler's Treat as Vacation > False and then Ageless Foreign > False for the homeworld for the sims left behind to have aged three days (I'm not sure about this, I almost never use that feature), but that kind of aging is really just incrementing all of the sims' total ages by 3, once each day each at midnight. It's not like they will have progressed or done anything when active gameplay is in the WA world. One could achieve the same thing using MasterController (MC Cheats module) once back home to add 3 to everyone's Relative Ages by way of City Hall upon return. Further, Treat as Vacation > False will require sims on the vacation to go to work/school if you ever add rabbitholes to the WA worlds that match their assigned careers. This may not be what you had in mind either.

Thanks for your reply! I think some of your ideas could be acceptable workarounds for me, thank you.
