Was wondering if anyone has her in their plaza today. I just want to get my 20 fortunes over with, not sure what my count is now but I know I'm more than half done. Gonna need multiple towns cuz I only play my mayor, no other characters
I don't think that visiting Katrina in other people's towns works. To get her PWP, it has to be characters that live in your own town when her tent is in your own town.
Maybe they changed it after the update, it took 20 weeks of visiting my own Katrina to get the PWP in my town back in 2013, and I visited lots of other Katrinas in other towns during those 20 weeks.
You're welcome to visit Katrina on my main street anytime, if it helps you to unlock the PWP. But her shop is closed today.
