AttackBuildingPriorit does work, but i only observe behavior change for when an AI has chosen which side to attack. for instance setting AttackBuildingPrioritBaracks(A) to 20,000 and AttackBuildingPrioritBaracks(H) to 10,000 does not make the AI attack the Atreides instead of the Harkonnen it only decides which building to attack when they are actually attacking a Faction's Base also setting it to 0,000 does not stop them from attacking the building when they are near it. on the Other hand if you set all buildings to 0,000 for the side the AI is inclined to attack first it does nothing or it ignores it(depending on unit type e.g stealth fremen behave oddly( observed berserk behavior or nothing)) even if all Other building belonging to different Factions/Houses have normal values 1,000-100,000
So Something is not right, i'm inclined to say AttackSide Priority is the Master setting(which doesn't seem to work) the only other explanation is the AI will always attack the closest enemy Base which means it's a rather dumb AI
