holy hand grenade collateral damage

[yeasties]

scenario: quest for the holy grail

situation: character is in the cave room with the vorpal bunny and the dead collector.

The main character throws the holy hand grenade to kill the bunny, but it also kills the dead collector and the game hangs.

edit: can reproduce by throwing the holy hand grenade on any node that contains the dead collector-the bunny is irrelevant
