I know I have been able to plant Citadels on City State occupied tiles,...even able to place them adjacent to the core of the CS,...But sometimes this isn't allowed - What are the conditions that make stealing land unavailable???
Yes, I know you need one of your territory's tiles next to the Citadel, and know I will lose influence,...I just don't understand what the conditions for this action to be performed?
Declaring War makes it immediately available (OBVIOUSLY), sometimes I can,....sometimes I can't...What gives? Friendship? Ally? Shouldn't I just lose influence, But still be able to perform the action?
