Hi, I have played GPGP before and just recently went back on playing the game again for a few months now. I am now at Day303 already but still stuck with having to investigate Dr Keh. I already asked for hints from Nasir (N), asked fellow suspects Alicante and Cicero as well as Flash. When I try to go to Dr. Keh to search for his pizzeria, I'm not able to do so! What went wrong on my investigation? Please help!
