Played the first faction mission in chapter 4 and got the doctor back to Erewhon... got the cut scene and then ran out through the blind to the chopper to do another mission and got the message I was too far from the doctor to go back. I assumed he had a mission for me so went back and he just stood there and I couldn't interact with him. The message wouldn't go away so I logged off and back on. The message was gone but I couldn't interact with him. Is this a bug or did I miss getting a mission from him?
