I finished my first foray into AI War 2 last night - the Helping Hands scenario. That was quite fun.
I wanted to explore custom campaign generator settings (I may be getting the name wrong) and as I played around with the various options I discovered that if I left and when to the main screen, then returned to the custom campaign settings, it would retain the settings I changed from default. For example, I set some faction to be ON and it kept that, while the default was OFF.
What I could not find is how to set those defaults back globally for the campaign generator. Did I miss some tick box or button?
