I'm currently doing a Ming > Mughals > Shan > Yuan run and I've noticed something that seems like a bug. After forming Mughals, you get permanent claims on all India. Now, after some time Ii formed Shand and Yuan) I got a whole bunch of messages about loosing clam in India. I loaded last save and I noticed that all my clams there are not permanent, but temporary. Is that intended behaviour? After forming another nation, all your permenent claims change into regular ones?
