Hi, as per your first save, I've played it for a few years and received numerous invitations to hunts, tournament as well as meet peers especially after top rulers stopped being in a war, while the AI is at war they will avoid activities, looking around the world shows that activities are clearly hosted, as for the second save, it's not useful as it's modded and crashes the vanilla game. If you happen to have any of the saves that are 100+ years into the game I'd love to take a look at them.
Cheers!
