So as part of the newest update, I've assigned birthplaces to the dragons that exist at game start. However due to limited time when making the update, I didn't figure out how to get it working on newborn dragons after game start. So just FYI, if you're wondering why some dragons have a birthplace, but your newly hatched ones don't, this is why. I'd like to work more on this and figure it out, but for the time being this update at least adds birthplaces for a bunch more characters (on the newest start date), and hopefully fixes some potential compatibility issues.
