This is the line that causes this PR to not compile. The problem is that you are trying to access CurrentGame but you specified the interface name ICurrentGameInfo instead of a variable holding an instance of an object. This doesn't work as to access a property you need an instance of an object type not the type itself that defines how that object looks like. So here you would need to get the current game properties to access this data.

Though in the map generator the current game has not been created yet. Instead the Generate method receives WorldGenerationSettings settings as a parameter, which will have this info. So that needs to be used to check the easter egg status either in this method or maybe this method could be not called in the first place if easter eggs are not enabled.
