Perhaps if a younger villager advances quicker in total skill level (not just one skill) but accumulative skill then maybe that villager jumps ahead in the age detail rotation order and takes on the name of the villager originally in that spot. You could apply that to the health bar too. Maybe the name glitch when sorted by age occurs if and when a villager’s health weakens and then gets better. *shrug* Just some thougts on the idea.
