I've also had this problem and hit "me too". I'd like to add my experience: I have a sim living on a residential lot in the Senbamachi neighbourhood in Mt. Komorebi. She has never travelled outside of Mt. Komorebi or taken a vacation. But she does regularly go up to the Yukimatsu neighbourhood to snowboard, ski and hike. The Frequent Traveller lifestyle has changed to "in progress" despite her never leaving her native world. I'm not sure if it's simply living in Mt. Komorebi or actively skiing, snowboarding and hiking that has triggered it, but I don't think the lifestyle should have been triggered.
I would like to add another minor issue related to the Frequent Traveler lifestyle, which is not a bug but is still something I would like to see addressed: if a sim with the Frequent Traveler lifestyle asks about home region to a sim who lives in Mt. Komorebi or any world that came out before it, they get a lovely blurb about the specifics of the world in question--but if they ask a sim who is from a world that came out after Snowy Escape (thus far Henford-on-Bagley or Tartosa), all they get is a generic "it's a nice place" message. It would be much appreciated if the sim gurus could add tailored blurbs for the two new worlds, and any other new worlds we might get going forward.
