This seems more like an oversight on the part of whoever is in charge of switching event NPCs on.
The past few years there has been a Moogle in Upper Jeuno during the Egg Hunt event. This moogle sold certain furnishings including the jeweled egg, which seems to be no longer obtainable from the Egg Hunt itself.
This year, the moogle is missing.
Could the Community Team please follow up with the appropriate people to see if we can get this switched on? I've seen a bunch of confused people running around Upper Jeuno because they want to buy a Jeweled Egg for their Mog House.
