Yeah, someone gave me detailed directions. Not exactly intuitive since that's the only place where doubling back works. I tried it in other places and it would restart, so I never tried it again.
Now there's a new problem. Screen goes black after the last step. I can still open the menu, but that's it. I'll try reloading a save and doing it again.
E: So there's still a map I can move around, but I can't see where I'm going since it's all dark. I was able to get sent back to the start and back to the clearing where the other mons are playing around. Turned up the brightness on my monitor and all I can see is the animation of grass as I walk through it. Is that intentional?
E2: I figured it out. Wasn't sticking close enough to the trees, had to be off the grass. Mildly infuriating, but at least it's over.
