Trapped sims disappearing ?

I have an evil sim who kidnaps other sims and locks them up in her basement.

Once the sims are in their cell I delete the door so there is no way they can leave ... yet every so often one will simply disappear.
The first three she 'caught' are still there , but the fourth and sixth sims just up and vanished (she has eight trapped down there at the moment)

So how come some can get out and others cant ?

I have the same problem (Sims 3). I randomly decided to make a female sim with the Heartbreaker aspiration so I make her lure random men in her basement, have a kid with them, and just keep them trapped in there.

So far it worked with 2 guys, I surrounded them with half-walls and let them starve. It was taking a while and I got impatient so I just lit up a fireplace and kept it lit up until a fire starts.

The first guy starved to death while being on fire which was funny to me. Second one burned to death.

As I saw that it was working, I went for a third guy right after my sim gave birth to the 2nd guy's daughter. At first I surrounded him with a normal wall and a door that was locked for everyone. He couldn't leave anywhere so I was happy.

But when he said the whole "It was nice but I gotta go" thing I quickly paused the game and moved the camera to him to see him complaining that he can't leave.

But NO! He just vanished!! I was disappointed but I tried again the next day. When I did, he did the exact sng; said he has to go and vanished. Is it a glitch? Is his job too important to be trapped in my basement? How???
