Starting to get frustrated with this game

[Taqwus]

Spell AI is one of the more problematic areas, I'd say. Last night, I spent some time trying to figure out why one of my Grand Thaugmaturgs was casting Vortex of Returning when the battle was being *won* -- vastly outnumbering enemy, some enemies Master Enslaved, enemy pretender paralyzed, nothing remaining that Nether Darts and the longdead couldn't handle. I'm still not sure what the trigger was; perhaps it was the damage done to an Ermorian Cultist standing next to a cold-aura Bane?
In addition, my Grand Thaugmaturgs, once they exhausted their scripts, ignored Relief (even when fatigue >= 90 for the Thaugs I used as communion slaves) and largely ignored Paralyze / Soul Slay / Nether Darts in favor of Reanimation spells, despite having more than enough spell power (16+ slaves, starshine skullcaps, Banner of the Northern Star, plus rune smasher/spell focus/astral clams on each master). T'was irritating, considering that the extra undead provided no benefit seeing as how they weren't able to engage due to the already-existing masses of undead. Relief should be higher priority when fatigue is up there, ground-pounder summons should be lower when there are troops in the way, weak undead summons should be very low priority when the numbers are already lopsided (e.g. ~600+ vs ~60, as that battle was IIRC). Bothersome.
(Vortex of Returning is... odd. There's a spell to take everybody home, but it only works in battle? Outside of battle, there's no ritual nearly that powerful, although none are capitol-restricted either.)
