Realized I’d never done this fishing quest, and I needed it to fish for the tuna and get the recipe. While I loved the fishing in the main game, fishing from the boat is/was tedious/dull and generally unrewarding, so I’ve barely done anything on/with it. Anyway, it took me a while but I caught my fish/recipe and I can now ignore the boat again.
For some reason during the cutscene, Prompto and Gladio turned invisible on me. >.>
