I had put up a knockout trap in one direction, and then assaulted the person. When he flees he hit my trap and falls unconscious (according to text), but the battle continues like nothing happens and he is able to flee again.. Short log.

Tac leaves up.
Tac has fled!

I can see both sides.
I can see that it could be that I wake him since he never leaves the room and therefore no big effect of the trap. Or he is knocked out and the combat should stop.

I am pretty sure this is by design, much like if a necromancer casts sleep on someone in combat, the next round they hit them and wake them back up.
