1. Maybe it's not a bug. Maybe it works like intended but I don't like it. First two pics show the situation. A unit with wider front attacks a unit with shorter front. Left and right flank of the unit with wider front run forward and don't notice that a fight started
. Sometimes they realize what's going on and attack enemy unit from the rear, sometimes they just form a crowd and do nothing. It doesn't make sense to me. AFAIK it was the first thing that soldier was learnt - to keep the line. IMO the whole unit should keep the line for a while after impact and then left and right flank should attack the left and right side of the enemy unit.
2. 3rd pic shows what's happened after a while. In the middle you can see two soldier fighting. They were fighting for about 10-15s while the rest of theirs units was standing doing nothing. It seems a little bit strange, doesn't it?
3. Check the ground texture in the distance (3rd pic). It looks like a kind of grid lines and it's not nice. I have radeon X1900XT 512mb and winXP SP3. All settings maxed out with HDR turned off.
