The NPC is located here on the left side of Lighthalzen!
They were unable to adjust the loyalty during maintenance on the 22nd, but have extended the event to November the 5th. You will need to talk to the NPC again.
Evolving the Homunculus into the adult form when it isn't 99 yet (assuming you can) won't have any effect on their stat growth, correct?
