[Alpha 17b] Warden does not offer recruitment pitch

[MiniKeeper]

Game is on Steam. My operating system is a laptop running windows 10.
On one of my save games (Cassandra Classic, intense difficulty, permadeath enabled) my warden, despite have a social skill of 11, was not recruiting any prisoners. I checked the social tab and it turns out the warden builds rapport with the prisoner, but never actually gives them a recruitment pitch.

I expected the warden to offer the recruitment pitch as usual.

To replicate:
1. Get a prisoner.
2. Enable "chat and recruit" on prisoner
3. Have warden talk to them while keeping the social tab open to observe social interaction

In addition, whenever the warden attempts what I think is the recruitment pitch, this comes up in the debug log;

For a save file, I used dev mode to get a prisoner and try to replicate the error. It worked, and it is where I got the debug log entry from. Save file is on dropbox.

I confirm. Warden build rapports, but no "recrutement" ever occurs. Adittionally, it is visible as a percentege numbers appear after an attempt - in fact, never.

I thought I noticed something similar, but I thought I caused it by interrupting the chat and recruit with a forced task. It seemed to go away after restarting the game.

I've loaded your savefile but couldn't reproduce it in A18, so I think it's already fixed. Thanks for reporting.
