i looked at the walk-through and when i get to "Proceed to Rockface Lower Layer, talk to Slaves. Return to Wan Hui, choose “Rockface,” unlock “Wan Hui Bio Data” CG, receive Empty Glass Bottle" what happens is that i tell wan hui about rockface then she tells me to go back to amelia after get some sort of headache. but when i go to amelia down at the starting area, theres nothing to do. am i missing something?
