I was using a jackhammer and I still got hungry, thirsty and tired. I’m sure it might be the same for any other manual labor things like cutting down trees and such too, but I haven’t checked them out yet.
Just checked, same thing for woodcutting.
Yeah, it seem like it should take less energy, but it doesn’t. Does it take less time?
Debug Life Support is supposed to make it so you Don’t need to eat, drink, or sleep. The only thing is, they didn’t code it to include activities that affect those needs. So I imagine anything that’s tiring to do will still affect the player naturally.
