The code is still crashing and it has something to do with how I'm
using the class field.
It is creating a database object but the object is broken. So that it
cannot then be edited. if I execute show on the object I get:
(show This)
{13} {13}
level "0D"
whos {11}
-> {13}
But what I want is
{13} (+Armour +Item)
level 0
whos {11}
-> {13}
I then end up in a situation where the broken object can be viewed
"{13}" shows up as a value in the class list, but can't be edited.
Pressing edit causes a problem due to the circular reference.
