nope not related... as i use 2 different functions one for equipment and one for the other items...
and that bug wouldn't cause the game to crash
and it looks like that the "Other Items" bug is a artifact from the earlier version....
i'm going to send you a new version of the item editor so you can test it to see if everything is working for you...
as i don't see any more bugs atm
====Update
i updated the furst post again and uploaded the newest version of the item editor (v1.0.4)
the only thing that doesnt seem to work well is
if some equipment have a negative attribute value (ATK,DEF,INT,HIT,GRD) the editor will save it as a negative value but the game wont care much about that and will read a a completely differen value (mainly as an insane high number for an attribute)
