In ye Dwarvish Outpost (board 4, "Citadel"), the three white-colored dwarves in the bottom left corner of the board share the same code via #bind-ing. The intended design is for them to die in two shots, with a brief invulnerability period, using two different :shot labels. However, since the dwarves are bound together, it's possible for both shot labels to be #zapped, resulting in unkillable enemies. The chances of this happening are multiplied by the fact that the dwarves #zap the shot labels multiple cycles after being shot, rather than immediately.

Note that the only dwarf that needs to be killed to progress is the red-colored "Dwarf Captain", so this bug is technically not game-breaking.
