Missing Spell: Calefaction

[strugglegenerator]

Thank you demonstar55. I didn't realize it was renamed to Dustdevil in 2006. I was able to find the spell, summon it's scroll and scribe it, but that's not Calefaction, it's a completely different spell (AoE) with the wrong levels, mana, range, etc.

Obviously I can edit this spell to be what Calefaction used to be, which is probably what I'll end up doing, but I would still like to know why I can't simply add a spell to the game using the method from my original post.
