A godly disease ?

I am not sure, but I belive there is a random chance to cure afflictions when called back. Atleast when my pretender dies heavily afflicted it usually comes back with just 1-2 afflictions. This is probably the case for diseased as well.

I just had a game against the AI where twice I took enemy capitals while they were still strong empires. Turn after turn after turn they kept being called back and I kept fighting them. They tended to have an affliction or two but they would change around each time.
