Yesterday I walked through the first two questd of EP 2 twice. On the first run I got achievements for complete investigations (Vidocq) and another one for complete search of the study. Unfortunately, I didn't receive either of them on the second run. Could you please clarify, what counts as requirements for these achievements? E.g. should I use all skill checks or simply use all available dialogues? It takes a lot of time and effort and lacks clarity. Same for the search - should you just check all the surroundings or pick up consumables, too? Please check, whether there are any bugs connected to these achievements.
Thank you very much! There's one other thing. When you meet Adams in Chapter 3 you can use your unlocked knowledge about her relationship with your mother ("I know"), but the following dialogue seems to be missing something. You say something like "I believe you knew my mother" and she answers "Do you think I made it all up?" - It seems like there should be something else between these lines.
