I had a graphical glitch last night as the carthaginians.
I was fighting in the north of italy, and one of my two units of regular (non-shooting) elefants was fighting some italians in a forest when I noticed that there were archers standing on the back of the elefants! I didn't see any of the archers fire though but it looked weird without a basket for them. They also looked much too big for the smaller elefants. I'm pretty sure (although not certain) that the archers weren't there when the battle started.
I also just had a ctd after clicking the battle summary window (total victory thank you...) .
