Islands of Mystery, Chapter 2: Dragon Wisdom

I wouldn't say I prefer more challenging levels, but this time, playing on a higher difficulty setting feels easier than playing on a lower difficulty setting last time. Game version 3.0. I only patch it for online play. But because of that... Oh! I downloaded the mod back when it was first fully released on the Dreammmod forum! Was there a limit back then? P.S.: And how did you rotate garrisons by 45 degrees in the first mission, since you can only rotate them by 90 degrees?
