I believe that I have seen the last of Polo and Nada. They bid me goodbye. I would chat with one once, then he would close off to me until the next time I saw him. Then the other one would do the same. This happened every time I saw them until they bid me goodbye. I haven’t seen them since.
I know that earlier this year, when I played back in February, that I could chat with each of them multiple times and that that was how to acquire the passes. Since I can’t do that this time I’m wondering if there is a new method or if they no longer dispense in the game.
