>>31586295it's right there, they're the "balls after delivering the parcel" ones. that's when you can start nuzlocking anyway. and i'm certain you find way more than 3 balls as hidden items/pokeballs after that point. maybe it was an effect of using the randomizer? it says nothing about changing item count though (i didnt touched the option to randomize items, by the way)
this is the last capturelog i had for Red, it's only missing the lapras you get in silph co instead of hitmonlee because i lost the save and had to redo that part so i went for lapras instead. at this point i had no more pokeballs and couldnt find more. pokemon marked with X died/ran away before i could try to capture them, so no pokeballs wasted
