I got knocked out in the ant nest, my friend got me up but I got stuck with -00 on the respawn timer though I could move about and interact everything was blurred and I couldn't get rid of it, when I selected give up back at base (in the escape menu) it killed me but I couldn't respawn and had to alt f4 to get out of it. When I loaded back in the game was jittery, when I attacked something it wouldn't let me swing so I died again, when I respawned I decided to go back to camp and when I went to open the door the game itself closed on me.
