So I just went through and re-beat every NPC that doesn't have a unique card as well as ones I know I'd played but didn't have all the cards from (even the one guy in Idyllshire and Lewena) because I'm apparently at 91 NPC's defeated. The tracker I'm using says there are 93 NPCs in the game and there is literally only one NPC I don't have access to so I REALLY don't understand how I have only 91 NPCs defeated.
Is there an NPC that is on trackers but the game doesn't actually count?
