Hi, I am currently stuck on the part where I got a fishing rod from this guy who needed medicine. I have tried fishing for nami everywhere in Ionia, I even went back to every single place that has water, and still no Nami. Everytime I fish for Nami, it either says "not even a nibble" or "it got away". Please help I have been stuck on this for days, by the way I'm playing on an emulator on my iPhone.
