Granting counties to a Local Noble sometimes makes them independent

[Trigparmandil]

(Order is backwards)

I used the "grant to local noble feature" for both Mitharin and Mekhrad, and Mitharin went independent. I was then able to vassalize in a few days. The same occurred when I tried granting it to a human courtier.
