The Frontier desk moved at the end of 2nd gens timeline in Season 5.0 of Frontier. According to game release dates and info I gathered this was when the discovery of White Espinas and hunting ban of Pariapuria removed. This according to release date was likely after the events of MHFU. And 6.0 when the hunting ban of Kamu and Nono is removed is during 3rd gens start.
