[0.952] Possible Bug - AI souvreign remaining on the map after the faction has rage quit (retired)

In a game I won via military conquest, one-by-one each sovereign would surrender and then just chill somewhere on the map.  

In the game I'm currently playing:

• If I get the sovereign to capitulate; I get him/her to control. He/she has all enchantments at the time of capitulation still active, and I don't have to pay upkeep on them. They all have that 'beaten' weakness, giving -25% accuracy.
• If the sovereign surrenders out of spite, I get what you see. He/she just stands there and you can do nothing about it.
• If the sovereign is wiped out...he's gone. Guess that's the only time those yoyos actually die. Personally, I'd like to control them in this instance aswell, though they should have a different weakness placed upon them than if they surrendured to you.

This just happened to me too. Queen Procipinee of Pariden just hangs around after she burned her last city to the ground.

I don't think you should control a sovereign after you defeat them. You should just have that satisfaction that you finally managed to kill the bastard. It's ok if you can control them if they capitulate. But they should definitely disappear of they resign.

EDIT: I killed Queen Procipinee again after she was left standing there and now she's gone for good.

This has happened to Karavox in my current game. If I mouse over him he's listed as "immobilized" for 1 turn. But the immobilization doesn't expire, the next turn the mouse-over says the same thing.

I was able to kill the sovereigns who resigned and they disappeared for good. It's still a bug, they just shouldn't be there in the first place.
