Hey,
I believe Nidbanes need a buff against other Hearthlings due to recent safety changes - apparently now they will only KO their target and disappear forever, without ever delivering the offender's skull to the Nidbane summoner.
Basically this allows any person ever to do whatever they please until they run out of HHP, and they can leave multiple scents without completely any repercussions (now Nidbanes will only kill their target if their HHP is very close to 0).
