Bug/Issue (BETA) Resting and gaining energy with no time consequence

I just recently bought the game and am playing in the Beta version w/ coop ext. I did notice that while being able to rest instead of sleeping for the night if the player is to keep the "Rest for the night" pop-up up no time will go by and the players energy level will still rise. I know that this could be non immersive for some players.

 

I think this is called "nap", but that during singleplayer time stops when in a menu and still recovers is a bug. It would make sense that it recovers a bit while just laying down in bed, but time flows tough.
