So I visited Corey's gym and I think I saw his ghost. I have at the moment 16 gym badges. I went back to Corey's gym because I felt like it. I'm wondering if I have activated some sidequest.
When I enter the Police Department, I get stuck at the entrance. It looks like the same kind of bug when I tried to enter East Gearen. A police agent talks to me and then I get stuck.
