note that the line above is where the error occurs.
that's your clue. it works in FScript, but not on unarchiving.
i would guess that it isn't archiving the item within? and storing off a 
value that isn't valid on unarchiving.
but then again... it the inspector is showing me the actual text that it 
is failing on, not some pointer thingy.
so, i don't know what.
post the answer if you figure it out.
i have only made half-way through the guide, so i am 1/2 past a total 
beginner.
fun stuff. almost no activity on this list. although i did get responses 
when i posted questions. from Philippe.
if you don't get an answer you could try emailing him directly. i got a 
response that way the first time i had a problem. actually, i note that 
you answered my first question on this list. hello, again.
