I just started a new campaign with IS, first time I've tried out this mod, and for some reason I've found that the AI is just recruiting armies of cavalry. While playing as prussia, my capital was just attacked by 10 units of cavalry. I'm not quite sure why this is, or if its normal. I am using this mod in conjunction with the AUM (extra units) mod for IS, but I don't know if that's what's causing this to happen.
