I was looking at armies to use in game day of armies and enemies of late imperial Rome. One army listed as enemy was western Patrician Roman II/82. This army does not, however, include later imperial — II/78 — As enemy. I have known Allies that were not reciprocal, But how was it possible for enemies to not be reciprocal? Is this an error or do people think or was there something behind it? They only overlap in one year 408. Notice below that late Roman have __II/82__ as an enemy; but II/80a does not have the late Roman as an enemy.
II/82a Western Patrician Roman Army: Terrain Type: Arable. Aggression: 0. Enemies: II/66, II/67b, II/71, II/72b, II/72c, II/72d, II/73, II/80a, II/80d, II/82a, II/83a, II/84, III/17. Allies: II/40 or II/58 or II/70 or II/72 or II/73 or II/80d or II/81a or II/81c or II/82b or II/83a.
Items in blue are simple mutual-enemy errors or date-mismatches, which players can check for themselves. Items in red are historical inclusion or omission errors, with a note to explain the reason for the change.
II/78a Western Late Romans (307 AD – 408 AD) ...no changes, as everything is correct.
