I had a situation when I was driving in a car and hit a zombie (it was Wednesday night) then I thought it was a regular NPC but it was a zombie, and when I killed him, a hazmat guy ran to his body.

Have you had such situations?? I thought the hazmat guy came to take his body, I wanted to see what would happen (the doctor's dialogue on the zombie's corpse) but I was hungry and I had to go..
