Is this really necessary - or maybe a bug I hope?

Opponent trips trap, fails to inhale noxious gas.

ok, i'll garrotte

He is guarding his neck too closely.

I haven't been able to tell if you can still be ko'd by a trap if you have the physical sleep protection timer - but you used to be able to get ko'd by a trap, then potentially get trap ko'd again (if trapper was lucky enough), or, at least, miss a ko trap, then get hit by the other one. (so the trapper can stack his odds with more traps/time/planning).

That being said, probably trap KO chance needs to go up a bit now that you can't stack a whole pile of the things in a room.
