I started the quest to find the escaped android from paradise falls. I've talked to Dr. Zimmer and the guidebook said I ionly need about 3 holotapes or any information for the Doc to tell me where Pinkerton is but I have given him like 4 or 5 holotapes but nothing. The quest arrow keeps going to Dr. Preston when I've already gotten information from him. What do I do?
P.S. I already know Pinkerton is in the Broken Bow part of Rivet City
