Bed Bug
When it's day-time and I tap the E button when close to a bed, the animation of my character getting in the bed is there, but I'm not sleeping (because it's day-time). Also, when it's night-time and I try to sleep again (with the sleeping character still in the bed (not me)) then I can't sleep.
And if I want to fix that, I have to break the bed and make a new one.
