Called into Sistan independence war without supporting Sistan, Transoxiana who I do support, does not join.

Allies of Sistan are prevented from joining because they are already fighting a war on the same side as the defender but their supporters are not. Same thing can happen with colonial independence wars but I'm not sure if the attacker takes that into consideration when deciding to declare war.

The rule causes other odd war behaviour too. Like you can attack a nation calling your ally to war and then conquer your ally's other ally without them being able to do anything about it(instead of letting that secondary participant ally accept the call-to-arms and create an automatic white peace for the first war if it does). More exceptions to the rule would be great in my opinion.

The attacker should at least be aware that the other vassals will not join in the independence war (when calculating feasibility)
