Before the desired message, check to see if the pointer is null or not.
This should be common practice with events since things can 'change'  so
easily.  Also, when the object disapears, make a check to see if the person
holding/wielding/carrying/etc the object is the same as the ch pointer (or
if !ch), then send a message to that person saying the item has disapeared.
 Get what I'm saying?

Yeah, grep around in places where you can find out who is carrying
something (ie, the immortal where, or locat object) and you'll get some
ideas.  Don't have any code in front of me, so I cant say off hand.
