I'm resetting for WonderCards and am after a spread on frame 5. I started the game, flipped the Journal twice, and then pressed A to speak with the delivery man before the lone wandering NPC in the Jubilife PokéMart could move or turn. The Arceus I got was on frame 6. I'm playing Diamond and I don't have any roamers out.
Anyone have any idea why I'm hitting frame 6 instead of 5?
The NPC could have barely started moving and you didn't notice it or you saved when the NPC was moving. That's all I could think of.
