I was at the prone position talking with my friend out of the game, the game was alttabed (-noPause at the launch parameters). When I got back the game I saw a zombie assaulting and battering me. And my character could not get up in animation. It was stuck at prone position but It could move and even run in every direction. So I ran away from the zombie for about 5-6 minutes (damn thing too stubborn)I was always on the ground for the animation but could run as fast. I cant recall if I could eat/bandage or if i did. Then I logged off on a hill. 1 day later(today) I joined the same server(public/regular), and I was sliding down the hill and I was ragdoll, I could not move at all. Also the graphics went potato.

I tried to take my clothes and item off and I did reconnect. Again I was sliding down away from my items as a ragdoll. Cant move, cant get up.
