I have two questions if someone could help me out.

The first is why does the computer, in campaign mode, refuse to siege me when in a battle? It will choose to siege a castle but then when i go to play the battle it simply stands there. I tried using XAI, hoping that might alter it and maybe the computer would attack but instead the units drop their siege equipment and walk away. I'm playing Stainless Steel 6.1 and patched up to 1.5, i'm not sure if that is the reason why, I wanted to ask here in case it was just a known problem. I can't imagine it is though, that seems like such an enormous problem I just can't believe it'd ever sneak into the final game.

Second, is there a way to play custom battle co-op? My friend and I would really like to play together on a team against a team of cpus. Why can't cpus be added in multiplayer, it just sees... silly that they can't.

Thanks in advance to anyone who has some answers or suggestions.
