I get the same error with the [number NaN] with the outgoing stat when meeting with jamie and I choose 'Resist the urge to bolt' option
Edit: Replayed it and got another NaN error, but with the formal casual stat when I choose 'Plaster on a large grin...' when jamie asks us whats our goal
Edit2: I also realize that when I choose ''I'm too good for this'' it rises the humble stat and the "everyone needs to review the basics" choice rises the arrogant stat
Edit3: same Number NaN error with the outgoing stat when choosing "can't believe you forgot about me" with alex
