Howdy 
I often play Demigod offline against AI, as I don't want to start an online game I may need to walk away from when I'm not sure I have time. When I first started playing, I'd select a map, then click on Auto Fill - 2 seconds to set up a match, all good 
Now that I'm playing against hard and nightmare AI's rather than normal, I can't use the Auto Fill option, as the AutoFill is only for normal difficulty.
Surely it wouldn't be too difficult to set the AutoFill to be a dropdown, where you can then select your desired difficulty level?
