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

[Meglobob]

The 'AI' in its all seeing wisdom as decieded that the enemy force you are facing is not strong enough to waste a fire gem on casting flaming arrows.

I had a good one recently, scripted on a 1F, 1S mage, communion master (2 communion slaves on the battlefield), phoniex power, flaming arrows. Mage had 1 fire gem, I am tight with my gems ok. Theory was he would have been 2F, 2S after communion, then 3F 2S after phoniex power, so no problem casting flaming arrows?

WRONG
The mage used the 1 fire gem to cast the phoniex power, it did not recognize the level gain from communion. So no flaming arrows...battle lost...army slaughtered...ARRAGH...
