I gave this childless, infirm 86 year old a Kingdom, thinking I'd get it back in a few years when I'd have another son. Of course the guy lives to 106 and miraculously has two sons.

Don't think I've ever seen an NPC live this long. Also, his wife was 45 or 46 at the time, I didn't think women could have babies at that age in the game.

Giving land to people who are about to pass is often a good strat if you need to get below the limit but want it back later. This time it backfired.
