I'm on Windows, on build number a10a70b.
I completed a mission to get a second opinion for a Professor, once I initiated that branch of the conversation with my contact, all their responses (regardless of my conversation choice) showed the same message: "I'm too busy to talk about that now." (Try when you have more perceived influence.)
Or something to that effect.
Once my contact thought of me as 'influential' the mission completed automatically, but gave no reward. (No reward was ever listed in my Deals tab either.) Immediately upon completion, I noticed a conversation option to talk about the 2nd opinion, the 'effects' text below the description was overlaid with something saying Missing String.
I moved the cursor, and the game crashed. See the attached error log.
