This question comes from a small bug, nothing important but something annoying.

In one campaign of our mod the only truly roman faction is julii, scipii are converted into italic peoples, and brutii and senate have disappeared (senate at the beginning of turn 0).

However, after several turns playing with a non-roman faction, we receive the message that romans are immersed in a civil war. But when I look into the diplomacy pannel, julii and scipii are allied.

Does anybody know how to stop this message or how to modify the conditions to be launched?
