when I heard the gunshots they were off in the distance, and I didnt hear any bullets hit near me, also later I ran into a guy that had a gun and told me he was shooting at zombies. Also after this event, I went out and found another set of pristine autumn hunter pants and I noticed an immediate difference in color and on the ruined pair the knees looked worn and faded, I remember first seeing this after crawling around, I was in first person and I looked down and saw the faded knees. Can crawling around affect the state of clothes? They probably got ruined when walking down a set of stairs but I really dont know what truly happened.
