In the 2nd story of the Fire Station, as you walk to the shelf, you take damage as if a zombie hits you which may or may not kill you instantly. If you survive your pants get ruined.

Also happened to me and a friend of mine. First, I broke my legs at the station in Severograd, and then my friend was killed at the station in Chernogorsk. My pants were ruined as well. This bug is present in all fire stations, I believe.
