Phoenix Pyre - AI overriding casting?

[geo981010]

Just to prove I'm not crazy, here is zip file with two turns from the same game that show the problem. The one zip has both turns plus the hacked map (so I could recreate it quickly).

The Tartarian who first overrides the Phoenix Pyre (Berg file - Tartarian is in province 77) and then 2 turns later decides to cast it ( Glanis file - same Tartarian is in province 69 this time). Phoenix Pyre was first in his queue and was researched, so I don't understand why it would override in this case. The spell doesn't use gems, and is not duplicating an effect you can get anyway else.

I had a pretender do such an override and die to a lucky Soul Slay - should have just cost him some fatigue and maybe an affliction, but instead died.
