Reinforcement battles - to CTD or not to CTD

[Harniac]

I had a CTD recently. Here are the details:

1) Factions - (Yours/Theirs)
Me - epirotes. AI - macedonians.

2) Circumstances - Siege battle? Rally? Open field? Bridge? Fort? Where and when (winter?) did it happen?
Siege battle. Me attacking with elephants, so no siege weaponry. No rallies during battle.

3) Leaders - Were they captains, generals, or family members?
I had Pyrrhos and one of his sons. Defending is the macedonian king, and the reinforcing enemy stack consists of a single general or family member.

4) Outcome - Level of victory/defeat, did any defeated stacks survive? How many units remained?
I won, but I didn't really note the level of victory or survivors, sorry. But I did run the battle twice, and both were CTD:s. I also tried autoresolve and had no CTD, but that's probably in order I guess.

5) Positioning - Were any of the stacks standing on siege graphics? On a land bridge? On a river crossing?
Two stacks are on siege graphics, my attacking stack and the reinforcing stack.

6) Version - EB Version (v.72, v.73a, v.74)
.74

7) Traits - Does the traits file found right here affect the CTD?
Haven't tried this.

8) Screen shots - If possible, please provide screen shots so we can see things like the units in each army, what year it was, whether there was a general, etc.
You get a save game instead (below).

9) Save game - If possible, please use a free file hosting service, such as Yousendit, to give us the opportunity to test it.
The save game, prior to the siege/battle (witch takes place in the same round due to the elephants) can be found here: http://www.totalwar.org/Downloads/Rt...arniac_ctd.zip

Feels good to contribute a little bit to this great mod!

1) Factions - (Yours/Theirs) I am KH, the enemy are Eleutheroi.
2) Circumstances - AI army attacks mine, which is besieging an AI city, and I have reinforcements.
3) Leaders - I can't remember, but the AI attackers were definitely captain led. The AI reinforcements might have been, I forgot. My attacked army was led by a family member, and my reinforcements were led by a captain.
4) Outcome - Clear victory, with the attacking AI army almost completely destroyed. The reinforcing AI army was not touched on the battlefield, but would have disappeared after the battle. My reinforcements never entered the battlefield.
5) Positioning - My attacked army was besieging. My reinforcement army was hiding in the woods, one tile to my Northwest. The AI attacking army was one tile to my East. The Reinforcements for the AI were one tile to my southeast, in Pergamon.
6) Version - EB Version (v.72, v.73a, v.74) .74
