Now, I know you're supposed to find a deserted ship up in the Rikuhu's Maw area, but I have no idea where it is. I scanned all over there, and I even looked it up in a YouTube video. My question is, why isn't popping up for me? Do I need to advance the main plot more? I still need to sail to Hasongo, but I've done everything after the Crookspur.
