Recently, I found that when attacking a mob/player the weapon is being displayed out as (null).
EX:
Your (null) does UNSPEAKABLE things to Dakkon Blackblade! [657]
Silence's Soul Blade draws life from Dakkon Blackblade.
Dakkon Blackblade is burned by Silence's Soul Blade.
Silence's Soul Blade freezes Dakkon Blackblade.
Dakkon Blackblade is struck by lightning from Silence's Soul Blade.

Dakkon Blackblade has quite a few wounds.

I kind of figure I either erased something or managed to hit a random key somewhere
as I was scrolling through fight.c. After comparing my fight.c damage output with
the original QuickMUD damage output, I couldn't find anything different in comparrison.
So, I was wondering if anyone else has ran into this problem, and possibly figured out
what it was that they did, or how to fix it.
(I'm not really wanting to back my code up to a point where this still worked.)

You can still compare your code to the previously working version and figure out what exactly you changed that broke this. It's obvious that you somehow messed up the short description for your weapon objects, but where you did that is anybody's guess at this point.

Either dam_message() or act(). Look for references of $p or $P as those are used to denote objects in most Diku-based games.
