Stock Areas and Killing Mobs

[Mike]

Alright..So I remove all the stock areas and redefine the vnum values in
Merc.h for the OBJ_SCHOOL_DAGGER and all that bull.  I make weapons that go
accordingly with these vnums in the area file i have.  I made a mob, but
whenever I try and kill anything, the game crashes.  explain please?
thanks a ton,
