I have the best double bed in the game and yet my male Vampire sim only gets one arrow, whilst his GF gets three. At first, I thought it was being in an apartment, but nope. I went and checked the best single bed, same thing. My male sim is only getting one arrow. I do have a few CC and he's got a lot of skills, but I don't see what it could be.
Edit: Update, he doesn't wake up with a full energy bar or with the well rested moodlet.
