looking at the code at [1]
there _should_ already be an if check for IS_NPC. The problem is more likely
in the char_to_room() line in the snippet:

  char_to_room(ch, real_room(number(SPIRIT_MIN, SPIRIT_MAX)));

If the rooms between SPIRIT_MIN and SPIRIT_MAX doesn't exist, real_room()
returns NOWHERE -> thus the log message above.

Actually dg_triggers.c:874 is more than likely to be

  if (!actor || !SCRIPT_CHECK(&world[IN_ROOM(actor)], WTRIG_COMMAND))

which will crash if IN_ROOM(actor) is NOWHERE.

In short, to fix the problem, adjust SPIRIT_MIN and SPIRIT_MAX to a range
of rooms that actually exists.


[1] It's common courtesy to at least put a link to the snippet into
    the post, so helpers have a chance to see what the problem is.
