I was on the mortuary's first floor. I killed all zombies up to that point. Today, this afternoon, I woke up and resumed my save, talked to Dhall for the first time, and completed the conversation.
I walked a little bit ahead while in the same room, quick saved, then pressed the map button. All of a sudden, the game stopped responding, and I got that error code.
