I've found some problems with the guards/archers:

• If they receive any damage, they don't heal until I reload the world.
• During nighttime, most guards stay inside the house of the villagers (sometimes they even start jumping on their beds)
  
  

And by the way, in my village there was a couple with a kid and I changed the name of the husband, but eventhough I reloaded the world, his wife and the kid were still related to the old name.
