I am starting a new run at the game using only the Gen 7 pokemon. However, this is looking to be more difficult than expected, as it appears that the only Gen 7 pokemon available pre-Julia is Grubbin (and that's only a 50/50 shot, replacing the Wingull/Panpour event). However, when I go to the building where the Wingull/Panpour used to be running around, it's empty. Is there something that needs to be done to trigger this event? I already have a pokesnax. Also are there any other Gen 7s that I am missing to catch before I fight Julia?
