This is still an issue.
I have indirectly lead Khergit Khanate to conquering Sarranid Sultanate and as soon as we were finished, Sanjar Khan started a war on Rhodocks just as I have planned. Then the indictment downpour started.
All I wanted is to deliver Khergit Khanate the complete rulership over Calradia. I didn't want to rebel or support a rebel. I like the life of a mercenary and only became a vassal to pledge my oaths to Sanjar Khan and have enough resources to support an adequate army for the campaign. Ruling a kingdom is a tough boring management job and I had hoped Sanjar Khan could accomplish that job on his own. I made friends with our marshall Tulug Noyan, Tonju, Alagur, Urumuda and married into his family; it was all looking so well until now.
It's been roughly a month or two since Sarranid Sultanate is no more(374 days since the start of the game) and my screen is overflowing with indictment messages, some lords join the Khanate after being indicted by their former rulers, receive a land and defect with it right away. Sanjar Khan just indicted Tonju Noyan, Alagur Noyan and our Marshall, Tulug Noyan — this, I think, was the last drop for me. I am seriously thinking of rebelling now even though we are pretty close with Sanjar Khan.
I guess this is the last time I am playing Native.
