I care more about if the rules are being broken than if and how the rules are enforced.
The intent of the vac mode seems painfully obvious to any bystander.
Are we to believe that protector is oblivious to why one of his cows that he was trying to negotiate to a province crown would time into vacation mode the tick after they give relations to a kd that can take its honor?
If some ****ty warring kd hides provs in vac mode at eoa to protect honor, they get called out, I see no reason not to do the same to BB.
