I had a mod called last man standing installed which essentially is suppose to give you a second chance at life if you are well rested... But I have since un-installed it and now whenever I die my character just either gets frozen sometimes or gets right back up everytime and I get a message "you cannot continue fighting" but I am healed to full life and am able to continue fighting as if I never died... Essentially my character is immortal, how can I fix this?
