So, the question is, are you sure it's a good idea to use something that works but has flaws?
Actually, it's a bit strange, I think I also tried to give a 3x3 size to a neutral creature, and there were no problems with the auto-win, but maybe I messed something up with the scripts, or it's because of other creatures in the army, I don't remember anymore.
Anyway, the other bugs remain.
And if not, should we make the Kraken boss a normal size?
