I did not receive the Luminaire Regular 2025 achievement yesterday (on the 18th day). Assuming I must have missed a day (though my achievement counter said I hadn't?) I waited to see what would happen today: when I visited Melody on the 19th, I received the achievement, along with this notification event:

I have now got that achievement, so it's all the same for me, but it seems like there must be something wrong in whatever code is tracking and awarding the achievement after 18 visits. Since this achievement, and Melody Regular, are planned to be retired promptly, it might not actually be able to achieve them with the exact number of visits.

This was addressed at this link.

Melody's Cottage Achievements Now Awarding Properly!View Feature

Fixed a bug where achievements like "Melody Regular 2025" and "Lumineve Regular 2025" weren't being awarded even when you hit the required number of visits. The progress was tracking correctly, but the actual achievement tier wasn't being granted. If you've been visiting Melody faithfully and were missing your achievement, just visit again tomorrow and it should pop![/quote]

Eww, that was messy copy and pasting on mobile from Kumos to Legacy!
