So I' ve been messing with the game for a few days. Rough Starts, but I knew puhing a little more would make me enjoy it.
And I do.

But now here is my situation. It's not my first playthrough, so I know what's what with being captured in Vendavel. In a previous Playthrough, I tried to escape from the hole. Bad idea. As I wanted to get my stuff back, I Went in and made myself prisonner and fought my way trough, and it worked perfectly well, until I got killed by some trog after falling to my fate because of my greediness (you know what I am talking about)

Anyway, This time, I got captured and I wanted to play the game. I am only day 6 and Aberdeen wait for my tribal favor, so I speeded up to get the 30 silver, and guess what ? There is NO dialogue option to give the money to the keeper !!!
I Was really happy because this time, I got a new skill that I didn' t know, made everything right, and now what ?
I am gonna save scumming like a common cheater, and try and try again until I manage to get out of here with all my stuff until the last iron scrap and get to Cierzo in time to give the favor. Which is a SHAME that the game, on top of being punishing as hell, is bugged to the bone !

Now maybe I will mess up things with the Vandavel quest ? I don' t know, but the game basically Leave me no choice. Oh yes, he is basically telling me, delete your save and try again. No. Not this time. If it fail I swear I delete this malware who don' t respect the player's time.

So I don't know if anybody has this bug, or know how to fix it, I' ll keep the save right before going into a killing spree just in case, because I really want to play nicely, but otherwise, it is what it is.

UPDATE : Just tried, not working. Game won't let me cheat to fix it's own buggyness. Bye bye outwad

It's not exactly a game breaking bug but it is poorly communicated in the game. I had the same issue but found the solution from Aegix_Drakan at https://www.reddit.com/r/outwardgame/comments/10mtguv/comment/j65ag74/:

"You not only need the silver for it, but you also need to do enough work to prove that you're not going to cause trouble.

Once you've done enough work, he'll be more sympathetic and thus be willing to let you out."

So once I mined some more, after sleeping a day or so for more iron to spawn, handed the iron to the lady collecting it, the guard let me out.
