In each one, you start off with or can gain "nests" of 4 breeding keeps by activating a trigger. The problem is, neither of these breeding keeps are able to produce any units or even technologies. I don't have too many upgrades on humans, but I've made breeding keeps before and know for a fact that I should be able to produce at least a few different units. So I'm not sure what exactly is causing it, but it seems to be something with the game.
The map says that I am supposed to be able to make dragons to help me, and without that help the maps are a lot more challenging, to point that I can't get past the third map without the use of a spell. Fixing this would allow me to get much more stars and gems, so I'd be grateful if that could be done.
