Javac,
Not sure if this is intentional but after extensive testing on difficult thefts I have been lead to believe that shoplifting has no positive effect on confidence levels after 30-45 minute stealing runs of mostly difficult targets. Is it possible to take a look at this and adjust if this is unintentional?
"Confidence is a Thief bonus that increases and decreases based on the success and failure of Thief-related activities. " Since thievery is our name sake it seems like our confidence should impact thievery and vis-versa.
