Yeah there are a couple of desciptions that are pretty hard to follow, but with a bit of common sense, its not that hard.
One example that i can remember was: Chapter 5, Poster 5
- Near the top of the excavation you descend some wooden stairs that lead down to a small depression in the cavern with another set of stairs leading up nearby and seceral crates scattered around the stone floor. Look under one of the staircases to find a chest hidden among some barrels. Open the chest to collect the last secret of the chapter.
Just not specific enough, what stairs are you reffering to, are there are A LOT in that area. Even if you just put 'after the suspension bridge' it would have made it a heap easier to find.
Still i was able to nut it out eventually
