Any Mods Or Similar?

EDIT:
SOLVED!!!
If it happens to you try everyday, mine worked after a week or so. If it still doesn't pop-up go with a friend in your party (my friend didn't have so maybe that's important idk).

ORIGINAL:
I can't get the "Somewhere in between" Secret Discovery and I don't know who I should talk to.
Any mods or similar that can help or at least tell me that is impossible... or anything?

All the details of my bug in a post in Bug Reports:

Sorry, not a native speaker.

P.S.: Added a screenshot of my Secret Discovery count. As you can see I have 14/16 on Wynn Plains, only missing Somewhere in between and the last one (as far as I know you need 15/16 to get that one).

 

As part of a daily routine" I repeated the "Somewhere in Between" secret discovery today. Only thing "new" is that I did it with a friend in my party. It worked and I now have the achievement.

Kinda sad both posts didn't get a single answer to clarify what I should (or could) have done in my situation. But happy I'm no longer missing that secret.
