Stuck in the Labyrinth

I'm stuck in the Labyrinth; Curly isn't by the sealed boulder. She should be there right?

The box where the Cure-All was is empty, and the Cure-All isn't in my inventory, so where's Curly?

 

Go back to the camp and talk to everyone half a dozen times, that always does the trick.

 

I'd already been back, but not in and out of the Camp. Thank you.
