The game had a meltdown with FPS as I was getting chased by 2, or 3, zombies. I ran to take cover in a building, and as I hit the action button, 'X', to close the door behind me it froze for 10 seconds with my character halfway in the building, and the door shutting behind me. After it unfroze, or caught up with rendering, my character was dead... If it didn't freeze, my character would still be alive!!! Is there any way this can be fixed???? The server was "SJ 4326", region: Americas. The city it happened in was Severograd.
