I've been under attack twice daily from spies for about two months, and can't identify them. I've got 50 spies, severe threat level and a good amount of land, and have ~100 tech for tech deals. How else can I improve my chances?
In a few days time I'm going on an expedition and won't be able to log in for 30 days. Is there any protocol as to how I can keep my nation alive and active?
