first off, sorry about the long title.

Ok, I don't have screenshots but I do believe that this can be recreated by anyone interested.

I was sieging a village, which has all of those weirdly placed road ways, and I was firing upon the sallying defenders with my Khazaks. While the enemy unit of viking raiders were walking along the road, my HA were firing upwards as if they were directly behind another unit to compensate for the buildings. Nothing new and amazing, until the unit of raiders got to a point where they were no longer behind buildings. The arrows, mid air, changed direction by about forty degrees and shot straight towards the raiders. I repeat, the arrows changed direction mid-air.

The only conclusion that I can draw from this is that the computer generates the attack and then the animations are a result of those generations. If the animation determined the kill, there would be absolutely no reason for the sudden change in direction for the arrows.

I know that I don't have screenshots, but my finger wasn't exactly on the printscreen button since I wasn't expecting it to happen. I'm sure that the scenario can indeed be recreated though.
