Why Don't My Mages Cast the Spells I Tell Them To?

[Nephelim]

There is more oddness with the AI overriding scripting.

I had a SC set to cast:

Body Ethereal
Luck
Quicken self
Attack rear

She was not otherwise ethereal (Neither through item nor naturally). Every single battle she did the same thing:

Astral Shield
Luck
Quicken Self
Attack rear

Body Ethereal requires no gems, and she was not already ethereal, I see no legitimate reason for the AI to override what I told it to do.
