I've noticed a strange thing, since I've finished OWB my Courier doesn't need to eat, drink or sleep anymore (I'm playing on hardcoe). Did it happened to anyone else or it is just my character turned into some kind of cyborg :wink_smile:

It always does this when you enter a DLC. I'm guessing they chose that since sleeping in the Sierra Madre was kind of an issue. Could also be to prevent some bugs, since some people reported dying upon reaching Zion because time automatically lept forward 2 weeks without them ever eating, drinking or sleeping.
Just go to bed, drink something or eat something and they should work again.
