Ridiculous "gameplay"

[GFX707]

OK, so here I am as the Greek Cities in about 220BC sieging rome with 4 armies of 1000-1500 (1 on each side) with 1 led by a family member (and another army of ~1500 led by my faction leader closeby) with the city completely surrounded. The 4 armies are all sieging and building siege engines and all by now have at least 2 rams, 2 sap points, 2 towers etc. versus large stone walls.

Then I get the message that the defenders are sallying and they attack one of the stacks without the family member (notice how they ALWAYS do this, even when there are 2 stacks, so you have to watch the AI controlled general suicide charge them and you can't choose which army to control) and I go to the battle setup screen....my army is there, and the Senate army led by their 5 star faction leader of about 1000 troops, and under reinforcements are the other 2 and the one controlled by my family member. Reasonable enough....

So the battle starts and there I am with 1 army (and a 13 minute time limit to take the city or the siege is broken off) and what do I see? A message pops up "Reinforcements delayed?"

Delayed? All 3 other armies that were SURROUNDING THE CITY? They somehow forgot that today we are having a battle? Why aren't they on the map with their siege engines? Where are they? They are sieging the city! How can all 3 be delayed????

So I start fighting with my captain whatever and I lose narrowly to the 5-star general, before any reinforcements show up (with about 5 minutes left I think) and my army routs, and it plays the sad music bla bla bla. Exit to campaign map.

What do I see?

ALL FOUR OF MY ARMIES are retreating back through Italy! Why???? They are all sieging the damn city and outnumber the defender more than 3 to 1 after that battle and they all retreat down to the bottom of Italy! 3 of them didn't see combat (although they damn well should have!!!!) and now all of a sudden they are running away and breaking the siege?

Things like that are just stupid!!!! CA, PLEASE address this!
