public class WorkGiver_Warden_BreakToNorigae : WorkGiver_Warden

    public override Job JobOnThing(Pawn pawn, Thing t, bool forced = false)

        Pawn prisoner = t as Pawn;
        if (prisoner == null || !prisoner.IsPrisonerOfColony) return null;

        if (prisoner.guest.interactionMode != DefDatabase<PrisonerInteractionModeDef>.GetNamed("Interaction_BreakToNorigae"))
        return null;

        if (!pawn.CanReserve(prisoner, 1, -1, null, forced)) return null;
        if (prisoner.guest.will > 0) return JobMaker.MakeJob(DefDatabase<JobDef>.GetNamed("Job_WardenSexBreak"), prisoner);
        return null;
    }
}

how can I solution.

It's about making the inmate a new slave settler.

'Pawn_GuestTracker' does not contain a definition for 'interactionMode' and does not have an accessible extended method 'interactionMode' that allows the first argument of the type 'Pawn_GuestTracker'. Make sure there is a using instruction or assembly reference.
