Game Mechanics: Push issue with Bane Of Nife

[Skuc]

I have now seen multiple times (twice in KC Pawbuster camp and once in Nagafen's lair on a Fire Giant Warrior) that Bane Of Nife is knocking mobs...apparently through the cieling. In KC, this caused Drolvarg Bodyguards to fly up into the "jail" area, summon me and cause major problems. The same happened this evening in Sol B, causing eventually a train to wipe our group.

Thanks!
