KO'ed AI sometimes gets killed instead

[geegee]

Sometimes - quite often in fact - when I KO an AI that I've sat in a chair or bench the AI will be killed.  Since I've set "no kills" in objectives, this loses the game through no fault of the player.  I've been managing this problem by reconfigure chairs (usually by giving more space so the AI isn't caught in geometry and bounced around) or simply eliminating the sitting entirely.  A problem is that such fixes aren't 100% reliable.  In some cases an AI that is usually just knocked out will die instead.  I can't figure a way to predict the problem or counter it.

My guess is that there isn't an absolute fix for this but I wonder how other mappers handle the problem.
