I'm not sure if this answers the real problem or no, but there was a bug in
the show() routine of Rogue 3.6 (and probably many descendants) that would
cause the appearance of a phantom trap when an invisible monster happened to
move over an undiscovered trap. The trap would appear on the screen, but
you couldn't identify it because YOU didn't discover it (something else did).
