Thanks for the interest!
Please upload a copy of the spell files off of each cd and I'll run a comparison of those.
As for some of the goofy differences (like Spirit of Wolf costing 0 mana) I did some looking into the spell file and most of the goofy things are happening due to duplicate spell effects further on down the file... my program was checking each line no matter what. I redid it to ignore effects further on down the file that it already checked once. This helped clear up a lot of the strange things. Those lines were probably just remnants or NPC spells or who knows, they may have not even been used in the game but here is an updated list, which makes more sense.
