Is there any circumstance in which the "Rested" sleep bonus does not happen after sleeping on a random bed? Just checking before report what I think is another PS3 bug...

If you are a Werewolf you won't get a bonus.

Werewolf blood prevents you from gaining resting bonuses from sleeping but other than that you could have a glitch once in a while and not get it or have a glitch that gives it to you from simply waiting (which is what I'm running into lately)...

I have had it a couple of times on PC as a normal character although I didn't search for the reason, it didn't seem important at the time.
