you gotta talk with Mona to get achievement

I tried in Chapter 5, the same that I select to collect the Urban legends that I was missing. When I talk with her she only says "wow that many" and then gives random clues on urban legends that I already have.

ok so heres the problem, you have to get all of them in one save then talk to Mona. just start in chapter 5 by using the chapter selector like how you did before and get ALL of them.

The problem is that I cannot take anymore picture of them, they look already all unlocked and not reactive to pictures... Even by doing New Game they are all still there.

I haven't run into this problem yet, but if the achievement breaks when you finish the urban legends across multiple playthroughs, a possible solution is to delete your persistent save data (game folder -> "Cloud" -> user id -> "user_stats") and replay up to Chapter 5, getting all of them in one run. (I'd recommend saving a copy of the file so that you can then put it back once you're done.)

If this is a bug, hopefully it gets fixed at some point. If there's a bug report contact, it may be a good idea to send this one in as something to look at.

Uff, just thinking in fighting the tiger again makes me dizzy. Maybe there is a profile save to remove without altering the progression, like resetting the ghostpedia but not the progress, does somebody know if this is possible?

I have this same problem. I love this game, but I do not want to replay it....
