The issue of my vassal not being able to take land from the state he declared war on

[Erdium 1]

I am playing with Türkiye and I have reached the perfect point. Albania is my vassal and Albania is declaring war on Italy and I am participating in this war, so far there is no problem.  Italy drops 5 atomic bombs on me, and I drop 10 atomic bombs on it. Of course, there is a huge loss. As a result, I conquer Italy completely, but this is my vassal, Albania, makes a peace treaty, but does not receive anything.


So I think this should be resolved
