I'm pretty sure people have mentioned killing off imprisoned sims before, but it seems that sims in the "imprisoned" role state (found by using the "show sim info" mod) are somehow designated unkillable? Their hunger motive suddenly jumps up even without actually eating anything.

I guess I sound like a psycho, but seriously, the whole thing in CL with neighbors entering with an "I know you won't mind, but even if you do, I'll stay anyway," or uninvited sims deciding to sleep in the sims bed (Of course, if you put an exhausted visiting toddler to sleep in a toddler bed, the sim will "react to inappropriate behavior," and immediately wake them up, but a random adult waltzing in uninvited and sleeping in the sim's bed, that's apparently appropriate. Nevermind that it's not.) ... really, is there any GOOD response to this? Even if you do the "ask to leave" interaction, they come back shortly after and do the same thing, again and again and again. Even if they've become enemies.

Googling yields everything from extremely horrifying RL situations to information about the Stanford Prison Experiment... but nothing relevant. Has a recent patch changed the way the game handles imprisoned intruders?
