Murphy bed death

I am playing an overstuffed household right now, the one with the upgraded and unupgraded Murphy beds. I've had no deaths and there's 14 sims in the house. It closed on them a couple of times in the beginning but nobody died. They had the negative moodlet and wouldn't go back to sleep after trying to open it or sleeping in it and it closing on them. They autonomously upgrade and repair them. I noticed one of the housemates repairing the broken bed while a sim slept in it. I did eventually upgrade the second bed to the one that has it break less often and I don't think it broke again for several nights. The fully upgraded one has never broken down again.
