Here is the situation : I am playing Byzantium, just declared war on Venice. Hungary is rival to Venice and Bohemia (Venice and Bohemia are allies) so I am thining great since they wont let Bohemian army throught since they are friendly with me.... ofc THEY let both of their rivals throught because Ragusa is in trade league with Venice... seriously ? I mean for real this is most retarded mechanics. Country lets two of their rivals throught becouse it gives miliatary access to some other country who is part of the war... can someone explain logic of that mechanics ?
