So I'm playing Fallout NV on the hardcore mode. I am eating and drinking just perfectly. but when it comes to waiting or resting for even 4 hours, when the resting box closes im lying dead on the ground from sleep deprivation, starvation, or something else. What is going on here? I thought I was supposed to sleep, lol, my character O'l Chateup Is gonna go crazy and start seeing gnomes. Which sounds fun, but what if one of the gnomes is actually a baddie.
