Heroes 6 - Discussion

So, my biggest fear didn't come true - the campaign is interesting to play.

I haven't noticed it yet... I completed the introductory mission - the last mission is boring due to its monotony. I started the campaign for Haven - they gave me a hero without a portrait, and even a Necromancer, although the city is human, but you can only build and upgrade the basic structures. But if you convert it into a Necropolis castle, all types of troops become available. For now, I'm playing with humans, relying on morale and willpower, but it's quite boring...

Koshka already raised this question, I'll repeat it: how to change the starting hero in regular maps? If there is an answer, please provide a link to it.

Also, the game crashes when I load a campaign save through the main menu. If I click "Campaign - Load," it seems to work.
