I decided to go back to the 360 version of SoD to get the Lifeline achievements since I never did. I rescued Sasquatch as soon as I got the call, and he's been at my base. I've rescued Vienna Cho, and have finished the main missions, all I have to do is call for extraction. But he has not given me a single Freak Hunt. Talking to him only let's me request him to follow. What do I have to do to get his missions to pop up?
