Presing claims for other kings as vassal

[opath]

Hey everybody,

i am not sure if it is known for a longer time as i have not played as a vassal very often but:
As King of Bavaria other kings whose claims i press become vassal to the Holy Roman emperor.
One was my nephew, the other one my son in law. Is it a (known) bug?

I thought vassalisation worked only for the person pressing the claim.

Sounds WAD to me. They are of your dynasty, so they become your vassal. But they are kings and so are you, so that vassal contract is broken, but since you are a vassal of the HRE, so will they.
