I tried to do the medical investigation for doc andrew in VC. I went to all the TSs, investigated, and hiked back to VC. I told Doc about all train stations, except San Francisco. He will not give me the dialogue to talk about SF. My pip says it is done and talk to doc andrew, but there is no dialogue option to say I found out more info for him. Gave it a couple of real days and tried again but still no. Is there something I am doing wrong? (forgive me if this is simple, I am pretty new)
