I don't know if this has been mentioned before, but I've found that if you rename a NPC, the ones you can hire and are running around the map, it doesn't change their name in the description about them.
Also it seems that there are a couple of instances of Kingdom names doing the same thing. When I got married it said that everyone in the Kingdom of Reland, or something like that, not Ryleth, the name of my Kingdom. Don't know if thats a lore thing based on faction deciding your overall kingdom or what.
Nothing big or all that important. Just something I've noticed.
