I submitted this bug to technical support, and they told me to come here, even though this sounds like something they should handle. I'm confused. Anyway...I am in the mission just after placing explosives on the plane, and the mission is to get the code to the guys house when he gives it to his three lieutenants. I have been able to listen to the entire conversation of all three, and guess what: no code. I have tried over and over and over, following him as closely as I can without getting caught, but still can't get the code. Am I doing something wrong? Or is this a legitimate glitch?

You need to use a sticky cam to record the conversation and then you will get the code. Just listening is not good enough. FIre one in their vacinity but not too close or they may notice it.

Yes, I'm sorry. I did that. To all three conversations. From beginning to end. Still no code.

Certain you are using a sticky cam and not a diversion cam?
