In my current game I’m best buddies with Rhoanna and we are both enemies and both at war with Einion Logos. Rhoanna is in the middle, I’m on the east and Eidolon is in the west. Rhoanna has a superior army, with mine roughly matching Einion Logos. So it all sounds good right? I wouldn’t expect Einion Logosto be able to get to me as he needs to cross the whole Rhoanna territory. But no, for some reason even though they are at war Rhoanna lets Eidolon walk freely and unhindered in his land, Einion Logos doesn’t pillage anything as he sends his troops across Rhoanna territory to surprise me, and Rhoanna just lets him walk freely, even though Rhoanna has vastly superior forces which could easily pick off Einion Logos units freely walking through his land. That means eidolon is free to make surprise attacks on my supply chain/re-enforcements that are walking through Rhoanna territory to the frontline, and also make surprise attacks on my territory (some of the boarders are right next to my cities due to Rhoannas huge culture). So what’s the deal? They are at war! Rhoanna is supposed to be my ally in this war, and he lets Einion Logos walk past his cities with a couple of strength 6 units, while his city is full of strength 8+ units, he could easily pick off Eidolons units casually walking past his city gates. Yes I checked, Rhoanna is still at war with Einion Logos, but he is treating this war more like a open boarder agreement then a war. Great War ally! He has no part to play in this war happening right in the middle of his territory; he just sits there with his popcorn and gets happy about our “mutual war effort” while watching the war comfortably from her palace couch.
