Heroes of Might and Magic V [Game Discussion]

I'm not trying to advertise anything, but I just wanted to share that I found a version of Heroes 5 called "Epic War Age." While the new creatures don't really interest me, I've noticed that the game seems to run more stably. I'm playing on the "Incredible" map, and I've only experienced one crash, even though I've played for a very long time. I can't say for sure if it's actually more stable, but this one example gives me hope.

Another thing: I have a mod installed that improves the AI. It seems to be included in the aforementioned build. I set the difficulty to "Hero." The AI divides its armies, giving the main hero the largest portion and the rest to the other heroes. But why is the AI so dumb that the creatures arriving in the castle in caravans just stand at the castle gates and accumulate? If the AI added them to its army, it would be much stronger!
Unfortunately, AI is AI, even in Africa...
