Pheonix bug

[shadoww1028]

I have been only using one stack of red dragons on my soothsayer killing everything that gets in my way (so far) until this fight. When ever he casts the spell I could not end the fight or it crashed. (poor exception handling...) I would send a unit to stand on the dead Phoenix and the game crashed, summoned or summoned but always a red dragon as that was my stack. Today I decided to bring a normal army I could now sand on the unit with out a crash (the cheap swordsman forgot the exact name). I completed the battle with heavy losses as it would be impossible to do otherwise. My game is of normal difficulty. But this got me around it.

This bug has been present since the original Kings bounty why do you just fix it?
