After I defeated Palmer and got Cid in my party, I got a ship to take out on the water. I docked the ship on the sand and went into the Canyon village to heal my party and when I went back to the world map the ship was gone. Is this a game breaking glitch or is it supposed to disappear and I'm missing something? I've walked up and down the entire coastline and the ship is definitely gone and I'm trapped now with nothing to further advance the storyline.
