I'm on Disc 2 and I'm in control of Cid where the group has to retrieve the huge materia. I landed the Highwind at the cave where you go into and cross some hills before you go into the Corel reactor. Now, thing is I went and did all the train stuff, got the huge materia and Ultima. Now when I exit, I'm outside Corel on the other side where the Gold Saucer is, and I can't find a way to get to the other side where I left the Highwind at the cave. Is there anything I can do?
