Well, perhaps it is related to Bodhi2.cre in some way, but for the looks of the error (to me) seems that the actual problem could be a certain "effect" in one of those items/abilities, somehow corrupted. If that is the case, should not the game crash again and come with the same assertion error if the effect is used by another creature/item?
I do have Improved Bodhi installed and working, and in my Bodhi2.cre file the only effect-related code is in her stats (proficiencies, inmunity to spell levels, movementrate bonus, etc...) and items (inmunity to +2 weapons and lower, stun, hold, chaos, imprisonment, etc...), that mimic some of her inmunities and perks as a powerful vampire.
I can send you my Bodhi2.cre if that helps to avoid the crash, but I would not place my bets on it.
