I think this is ok with the rules, but it seems wrong...
Heroes have an outdoor encounter. One of them is down to 2 wounds and has 2 bleed tokens. Chances are that he will die in his turn. So the heroes do all the other heroes turns first, and manage to kill all the monsters. It doesnt say so explicitly, but I think at this point the encounter is over immediately. Bleed tokens removed, hero still alive.
It just seems wrong....
