Vassal declaring war on a senior

[Przemol 2]

When I conquer a country and I vassalize it, it still has it's old alliances. Because of that fact when I attack it's ally, my vassal declare war on me and even if I win the war it stays independent.

To solve this problem I would block the alliance option to the vassals.
