I just bought RPG Maker MV yesterday and I've worked my way through videos and guides, but I am stuck on a part. I'm trying to set up an event, that will progress my story, but only after i get 3 characters in my party, and talk to a specific NPC, how do I go about doing this? I need it to be like i talk to the NPC, get the three characters, then go back to the NPC to progress the story, how do i do this?
