It seems there's an issue where the map mixes up the levels of griffins and monks - https://c2n.me/4754zPj is an example of the distribution. Also, it will turn out that griffins cannot be chosen as sworn enemies - in the standard version, this also happened in the battle with elves, but there, a second battle was possible for the griffin. Perhaps the same applies to bears and berserkers. I understand that neutral creatures didn't appear in the random distribution.
Another point: does random creature enhancement imply that some type of creature may remain unenhanced, or will something from the enhanced creatures definitely appear? Because having 3 types of troops is more fun than two; in my case, everything was enhanced.
