Premade Sims: Place Sims 4 in the "main universe" timeline:

Remember: other worlds like Riverview, Shang Simla, Champs Les Sims, Al Simhara, Sims University, Hidden Springs, etc happen during SUnset Valley timeline, while som happend 25 years before, later etc... I won't promise anything, cuz its too much work for me and too many sims for a single save file. I'll keep working on updates for this save file, tho. So you can expect something from there.
