I'm locked into myshkino tents in the officers barracks because I shot some zombies that came in after me,,, but something is hitting me that I can't see, it started outside trying to help someone with equipment,, I was trying to give him gear and something kept hitting me. Another time I was shooting zombies chasing a guy that had no gear and was trying to gear up, and out of nowhere something started hitting me,, so I backed up to see what it was and the hits were coming out of thin air. What is going on ? How do I fix it ? or is it a server problem ?
