Editor: Autocalc on spells doesn't automatically calculate magicka cost
In vanilla autocalc is used to both add the spells to NPCs with the autocalc flag AND to automatically calculate the cost of the spell based on the effects in the same way custom spells do. This doesn't seem to work at all in OpenMW, the cost value of the spell is preserved whether autocalc is enabled or not and toggling it in the CS doesn't change the cost (or adding new effects).
Note that the game calculates the spell in the CS and not the actual engine so this is for OpenMW-CS
